Prefer `+` concatenation over template literals, just feels easier to read

+ minor naming tweaks

- no longer building text scratch 🎉

- update `middle` to dogfood `startEndAt` function

- use `alternating` logic from `middle` for more granular truncation (was previously truncating 2 chars at a time)

- allow testing greater than 100 lines

+ fix resize observer on load - initial logic is off due to font not yet loading in

- update beta warning - ~100 lines is fairly snappy at this point, and # of characters should no longer be a factor

- underlying mechanism is better described in new comment above ratio utils

and make canvas the only rendering method

+ change class inheritance - I'm making canvas text utils its own separate import because there's another component in another PR that will be able to use it soon, that doesn't need truncation logic

+ remove `measurementRenderAPI` prop

+ revert debugging in source code

+ update copy/recommendations
