Update to 1.1.1:

Version 1.1.1

* Updated all files to reflect new email address for maintainer:
  micah@addictivecode.org (previous address, micah@cowan.name, is no
  longer valid)

* Added links in the (Texinfo) manual to playable videos that
  demonstrate basic teseq functionality, and how to use teseq to create
  _and edit_ interactive terminal demos:

  * https://asciinema.org/a/7443
  * https://asciinema.org/a/7445

* Added example in the manual for using teseq to strip escapes out of a
  typescript file.

* Note: a new (optional) build dependency has been introduced:
  pkg-config, which is now used to find whether libcheck is installed.

* BUG FIX: Fixed an issue where teseq could spin indefinitely churning
  out \xFF bytes on no further input. Input from a command such as
    $ printf '\033!!\177'
  would produce this issue.

  This issue was discovered by means of american fuzzy lop,
  http://lcamtuf.coredump.cx/afl/

* BUG FIX: Fixed an issue with \x7F (DEL) being treated as a valid final
  character for control sequences, and being printed on teseq's output
  (which should not be printing non-whitespace control characters).
