Home / integration in std

For comfortable work with basic_integer in Standard Template Library (STL) added function and structure overloads.

**Functions**
`swap`	overload for `std::swap`
`operator>>`	input from `std::basic_istream`
`operator<<`	output to `std::basic_ostream`
`to_string`	converts integer to `std::string`
`strtoull strtoll`	converts C-string to (un)signed integer
`to_chars`	converts integer to fixed size character buffer since C++17
`from_chars`	converts fixed size character buffer to integer since C++17

**Structures**
`is_integral`	returns `std::true_type` for integer type
`is_unsigned is_signed`	returns `std::true_type` for (un)signed integer type
`make_unsigned make_signed`	returns equivalent (un)signed version for integer type
`numeric_limits`	information about integer type
`hash`	returns FNV-1a 64-bit hash from bytes of integer
`formatter`	used in functions `std::format`, `std::print` and etc. since C++20
