This updates `fmt` to the latest version and moves to just being a copy of their repo to make updating easier (no editing their cmake / figuring out which files to minimally include). The motivation for this is now that we switched to C++ 20, there were a ton of deprecated function usages that is going away in future compiler versions. This gets rid of all those warnings. |

Running the fuzzers locally
There is a helper script to build the fuzzers, which has only been tested on Debian and Ubuntu linux so far. There should be no problems fuzzing on Windows (using clang>=8) or on Mac, but the script will probably not work out of the box.
Something along
mkdir build
cd build
export CXX=clang++
export CXXFLAGS="-fsanitize=fuzzer-no-link -DFUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION= -g"
cmake .. -DFMT_SAFE_DURATION_CAST=On -DFMT_FUZZ=On -DFMT_FUZZ_LINKMAIN=Off -DFMT_FUZZ_LDFLAGS="-fsanitize=fuzzer"
cmake --build .
should work to build the fuzzers for all platforms which clang supports.
Execute a fuzzer with for instance
cd build
export UBSAN_OPTIONS=halt_on_error=1
mkdir out_chrono
bin/fuzzer_chrono_duration out_chrono
