feat: Generic numerical types Inspired by https://github.com/josdejong/mathjs/discussions/2212 and https://github.com/josdejong/mathjs/issues/2585. Provides a simple adapter function `adapted` which takes a class implementing an arithmetical datatype and returns a PocomathInstance with a new type for that class, invoking the methods of the class in a standard way for the Pocomath/mathjs operations. (That instance can then be installed in another to add the new type to any instance you like, including the default one.) Uses this facility to bring fraction.js Fraction into Pocomath, and tests the resulting type. Currently the "standard" interface for an arithmetical type is heavily modeled after the design of fraction.js, but with experience with other 3rd-party types it could be streamlined to something pretty generic (and the Fraction adaptation could be patched to conform to the resulting "standard"). Or a proposal along the lines of https://github.com/josdejong/mathjs/discussions/2212 could be adopted, and a shim could be added to fraction.js to conform to that standard.
