* - try fixing the warning "chrono.h:1217:37: warning: conversion from 'std::make_unsigned<long long int>::type' {aka 'long long unsigned int'} to 'size_t' {aka 'unsigned int'} may change value [-Wconversion]" by casting int to size_t (occurs when cross-compiling to Raspberry Pi ARMv7)
* - remove call to to_unsigned() because using static_cast<size_t> is enough
* Add support for subsecond printing for std::chrono::duration according to the c++20 standard
* Remove assert test that overflows intmax_t
* * Hopefully fix int64_t to int32_t conversion errors.
* Allow proper Duration::rep type to propagate via template argument deduction
* * Hopefully fix int64_t to int32_t conversion errors.
* Allow proper Duration::rep type to propagate via template argument deduction
* Fix sign conversion (-Wsign-conversion) warning treated as error in num_digits()
* Format chrono.h with clang-format
* Remove extra forward slash in doxygen style comment

* Apply all suggestions from GitHub, except for replacing the utility subsecond_helper class with a function
* * Move logic of handling subseconds from utility class to function with name write_fractional_seconds()
* Revert write(Rep value, int width) function to previous state
* Fix -Wshadow warning
* Remove unsued get_subseconds() function, its logic has been moved to write_fractional_seconds()
* Change comment from lowercase int to uppercase Int
* Simplify test check
* Integrate suggested changes
* Remove static from detail functions, they are no longer member functions of a class and static is unnecessary.
* Change comment from "amount" to "number"
