Added Types:

Unsigned integers: All uint types from uint8 to uint256 in steps of 8 bits (uint8, uint16, uint24, uint32, ..., uint248, uint256)
Signed integers: All int types from int8 to int256 in steps of 8 bits (int8, int16, int24, int32, ..., int248, int256)

Improved Validation Functions:

Simplified _validateUintType and _validateIntType to use the TYPE_LIMITS object dynamically instead of hard-coding each case
This makes the code more maintainable and eliminates repetition

Total Types Added:

31 uint types (plus the existing uint alias for uint256)
31 int types (plus the existing int alias for int256)

The validation functions now handle all these types automatically through the TYPE_LIMITS lookup, making your code much more comprehensive while remaining clean and maintainable. This covers all possible integer types that Solidity supports, from the smallest 8-bit integers to the largest 256-bit integers.
