🐛 Implicit sign conversion warning in clang in c++17 and 20 modes (#2009) 
Problem:
- On Apple clang version 11.0.3 (clang-1103.0.32.62) in C++17 and C++20
  mode, clang 11.0.0 in C++17 and C++20 mode, and clang 9.0.1 in C++17
  mode, the following error is generated:

                     ^
    2 errors generated.

Solution:
- Explicitly cast the result of the subtraction to the (unsigned) outer
  type.

🔧 Silence useless cast warnings (#2008) 
Problem:
- gcc-10 is generating the following warning at all standards:

    test/format-test.cc: In member function 'virtual void UtilTest_BitCast_Test::TestBody()':
    test/format-test.cc:108:42: error: useless cast to type 'uint64_t' {aka 'long long unsigned int'} [-Werror=useless-cast]
      108 |   s = fmt::detail::bit_cast<uint32_pair>(uint64_t(~0ull));
          |                                          ^~~~~~~~~~~~~~~
- gcc-8 is generating the following warning at all standards:
    test/format-test.cc: In member function 'virtual void UtilTest_BitCast_Test::TestBody()':
    test/format-test.cc:108:56: error: useless cast to type 'uint64_t' {aka 'long long unsigned int'} [-Werror=useless-cast]
       s = fmt::detail::bit_cast<uint32_pair>(uint64_t(~0ull));
                                                        ^
Solution:
- Cast 0 to a 64 unsigned bit int and then invert.

🎨 [CI] Specify the exact version of clang to use (#1991) 
Problem:
- The version of clang to use is specified only as `clang++`. This is
  inconsistent with the specifications for gcc and exposed to unexpected
  failure if the default changes.

Solution:
- Specify the exact version of clang to use. I chose `clang++-9` as that
  is the version that `clang++` is currently resolving to.
