conversions std::charconv

[gpeterhoff]

It would be very helpful to have conversion contruructors/conversion operators directly in from_chars_result/to_chars_result. You use boost/core/detail/string_view yourself, as the compatibility is provided.
A customized cast is required for chars_format.

Is the template from_chars_result_t really necessary?

from_chars_result.hpp.txt
to_chars_result.hpp.txt
