Is help wanted?

I'm interested in two topics for boost::crc:
1. Add optional standalone support. Currently all crc's dependencies can be supplied by standard library (except boost::uint_t<>) starting from a certain standard
2. Add constexpr support, so crc can be calculated at compile time

Is it any chance it can be accepted in this library or it is better not to try and make my own personal fork with desired changes and call it a day?

It is worrying sign that some of existing issues and PR has absolutely no feedback or activity, so I fear making a proper PR could be waste of time if there is nobody to process it.
