Log message:
comms/py-esptool: Update to 4.1

Mark as not for python 2.7.

Summary of upstream release notes, less bugfixes:

* Version 4.1

    ESP32-C2: Added flash encryption support
    elf2image: Added argument to disable appending SHA256 digests

* Version 4.0

Starting from v4.0.0, esptool adopts the semantic versioning
specification, please read the related "Versions" esptool
documentation page when deciding which version to use.

** Breaking changes

  Public API has been defined by limiting access to internals that
  have been refactored into multiple source files. Changing or
  refactoring these limited internals won't be considered a breaking
  change in future releases. Migration is easy and self-explanatory
  (you will get an import error if something has moved) and is
  required only in projects that import esptool directly.

  If active security features are detected, the default behavior
  changes to prevent unintentional bricking (#699):

    If flash encryption is enabled, erase_flash and erase_region
    cannot be executed.

    If secure boot is enabled, erase_flash, erase_region and
    write_flash operations cannot be performed (write_flash is just
    restricted to protect the bootloader region 0x0000->0x8000).

    An override flag --force lets the users execute these operations
    anyways.

  Flash parameters in an image header can now be changed only when no
  SHA256 digest is appended (espressif/esp-idf#8798).

  Python versions 2.7, 3.4, 3.5, and 3.6 have been deprecated, the
  code is now Python 3-only compatible. Releases v4 and later can't be
  installed from PyPI on these deprecated Python versions.

  The ESP8684 alias has been removed, ESP32-C2 has to be used.

  Megabit flash sizes have been deprecated, use megabyte units from
  now on.

** New Features

   Added stub flasher support for ESP32-C2 ECO1, deprecated ECO0 stub (can still \ 
be used with ROM).

   espefuse.py: Added a new package - ESP32-D0WDR2-V3

Log message:
*: convert to versioned_dependencies for py-cryptography

Log message:
py-esptool: updated to 3.3

Version 3.3

New Features

Added stub flasher support for ESP32-C2.
Added --flash-mmu-page-size option to change flash MMU page size on ESP32-C2.
Added address and dummy cycles configuration to SPI flash commands, allowed \ 
reading flash SFDP registers.
Added target-specific flash frequency options.

espsecure.py

Added support for ECDSA P192 and P256 signatures in Secure Boot V2.
Refined Secure Boot V2 ECC support.
Added support for XTS_AES_128 using 128 bit key FE scheme.

espefuse.py

Added execute_scripts nesting support, a script can now be called from another \ 
script.
Added ESP32-C2 espefuse.py support.
Fixed power-out time for VDDQ settings for ESP32-S3.

Internal features

These features are intended for use inside Espressif:

Preview support for ESP32-H2-beta2 has been added. This SoC is not generally \ 
available, so it is unsupported in this release. Official support will be added \ 
in a later esptool.py release.

Bug Fixes

Fixed autodetection on ESP32-S2 in USB-OTG mode.
Fixed flash.rodata not being recognized as part of IRAM in the ELF parser.
Fixed wrong UART_RXFIFO_CNT_M mask values in the stub flasher.
Added overerase detection and a fix sequence for certain XMC flash chips.
Allowed USB PID detection for USB-JTAG-Serial mode on lowercase port names.
Fixed chip autodetection to work in secure download mode.
Fixed wrong firmware image being returned for beta chips.
Fixed a wrong bootloader flashing offset on ESP32-S3.

Miscellaneous Changes

Launched a new self-hosted esptool.py documentation and heavily updated its contents.
Renamed the ESP8684 target to ESP32-C2 (added alias for compatibility).
Added a warning for flash sizes that are not supported by the stub flasher.

Log message:

Added a security confirmation flag to espefuse tests.

Internal features

These features are intended for use inside Espressif:

Preview support for ESP32-H2 and ESP8684 has been added. These SoCs are not \ 
generally available, so they are unsupported in this release. Official support \ 
will be added in a later esptool release.
Added automatic delay for boot time after ESP32 reset in FPGA.
