feat(algebra/continued_fractions): add computation definitions and basic translation lemmas (#2797)

What

  • add definitions of the computation of a continued fraction for a given value (in a given floor field)
  • add very basic, mostly technical lemmas to convert between the different structures used by the computation

Why

  • I want to be able to compute the continued fraction of a value. I next will add termination, approximation, and correctness lemmas for the definitions in this commit (I already have them lying around on my PC for ages :cold_sweat: )
  • The technical lemmas are needed for the next bunch of commits.

How

  • Follow the straightforward approach as described, for example, on Wikipedia
