fmtlib: updated to 8.0.1

8.0.1:
Fixed the version number in the inline namespace
Added a missing presentation type check for std::string
Fixed a linkage error when mixing code built with clang and gcc
Fixed documentation issues
Removed dead code in FP formatter
Fixed various warnings and compilation issues

8.0.0:
Enabled compile-time format string check by default.
Added compile-time formatting
Optimized handling of format specifiers during format string compilation. For example, hexadecimal formatting ("{:x}") is now 3-7x faster than before when using format_to with format string compilation and a stack-allocated buffer
Added the _cf user-defined literal to represent a compiled format string. It can be used instead of the FMT_COMPILE macro
Format string compilation now requires format functions of formatter specializations for user-defined types to be const
Added UDL-based named argument support to format string compilation
Added format string compilation support to fmt::print
Added initial support for compiling {fmt} as a C++20 module
Made symbols private by default reducing shared library size. For example there was a ~15% reported reduction on one platform
Optimized includes making the result of preprocessing fmt/format.h ~20% smaller with libstdc++/C++20 and slightly improving build times
Added support of ranges with non-const begin / end
Added support of std::byte and other formattable types to fmt::join
Implemented the default format for std::chrono::system_clock
Made more chrono specifiers locale independent by default. Use the 'L' specifier to get localized formatting.
Improved locale handling in chrono formatting
