Detailed Description

Convert a printf-style format string to a std::formatter-style one, and prepare any casts that are required to wrap the arguments to retain printf compatibility.

This class is expecting to work on the already-cooked format string (i.e. all the escapes have been converted) so we have to convert them back. This means that we might not convert them back using the same form.
