Research direction

Start by reviewing the Stringize, Latexize, and ToSympy implementations, then read the related discussion in #392. Done means the v3 API direction for reducing string allocations and the appropriate StringBuilder or alternative approach are agreed and documented.

Written by the indexing model from the issue text.

Description

Proposal

Using this many strings is suboptimal. Passing a StringBuilder (are there more efficient alternatives?) around would be more optimal. This changes the API surface so is v3 work. Related: #392
