Updated all the dependencies and addressed dependabot warnings from 12
to 20, starting at
https://github.com/coredhcp/coredhcp/security/dependabot/12 .
This also required dropping Go 1.14/1.15 and bump to the latest two
versions, 1.19 and 1.20.

This is a sentinel error that downstream users should be able to compare
against to identify when the allocator is out of addresses, move it from
the bitmap allocator package to the general allocator interface package

This allocator was not safe for concurrent access. Add a simple lock
around operations on the bitmap itself to protect from that

Allocators themselves are implementation details for now; bitmap
reflects better the properties of this allocator
