1.4.1

Fixes:

• Properly erroring for invalid Enum keys

New Features:

• Added custom_read and custom_write flag support to glz::meta, which can solve ambiguous partial template specialization (see custom-serialization.md)
• Added error_on_const_read compile time option to glz::opts, which will produce errors if an attempt is made to read into a const value (the default behavior is still to skip the value)

Internal Improvements:

• Using .erase rather than .resize where appropriate when reducing lengths of array like types
