fmtlib: updated to 6.0.0

6.0.0:
Switched to the MIT license with an optional exception that allows distributing \ 
binary code without attribution.
Floating-point formatting is now locale-independent by default.
Added an experimental Grisu floating-point formatting algorithm implementation \ 
(disabled by default). To enable it compile with the FMT_USE_GRISU macro defined \ 
to 1.
Separated formatting and parsing contexts for consistency with C++20 \ 
std::format, removing the undocumented basic_format_context::parse_context() \ 
function.
Added oss-fuzz support.
formatter specializations now always take precedence over operator<<.
Introduced the experimental fmt::compile function that does format string \ 
compilation.
Added the % format specifier that formats floating-point values as percentages.
Implemented precision for floating-point durations.
Implemented chrono format specifiers %Q and %q that give the value and the unit \ 
respectively .
Fixed handling of dynamic width in chrono formatter.
Removed deprecated fmt/time.h. Use fmt/chrono.h instead.
Added fmt::format and fmt::vformat overloads that take text_style.
Removed the deprecated color API (print_colored). Use the new API, namely print \ 
overloads that take text_style instead.
Made std::unique_ptr and std::shared_ptr formattable as pointers via fmt::ptr.
Made print and vprint report I/O errors.
Marked deprecated APIs with the [[deprecated]] attribute and removed internal \ 
uses of deprecated APIs.
Modernized the codebase using more C++11 features and removing workarounds. Most \ 
importantly, buffer_context is now an alias template, so use \ 
buffer_context<T> instead of buffer_context<T>::type. These features \ 
require GCC 4.8 or later.
formatter specializations now always take precedence over implicit conversions \ 
to int and the undocumented convert_to_int trait is now deprecated.
Moved the undocumented basic_writer, writer, and wwriter types to the internal \ 
namespace.
Removed deprecated basic_format_context::begin(). Use out() instead.
Disallowed passing the result of join as an lvalue to prevent misuse.
Refactored the undocumented structs that represent parsed format specifiers to \ 
simplify the API and allow multibyte fill.
Moved SFINAE to template parameters to reduce symbol sizes.
Switched to fputws for writing wide strings so that it's no longer required to \ 
call _setmode on Windows.
