@coven/math refactor

[loucyx]

This PR introduces a refactor for @coven/math to make it more robust and fast. Internally now never does operations with number values, only Precise values (tuple of bigint), and only converts to and from number on surface utilities (like calculate). For edge cases like NaN or Infinity, it has a fallback to regular math operations.

Besides that we are introducing a new getGroups util in @coven/expression to make cleaner and safer use of named capture groups. Some libraries that previously were doing use of ?.groups are now using this util.

memoFunction now returns a frozen function, so it can't be mutated.

In @coven/types we have a new ExpectedStringables to create a string type that requires the existence of a set of Stringables.
