[improvemnet] drop crc, Buffer dependency (#1673)
This PR incorporates a crc method from https://github.com/alexgorbatchev/crc into the library, removing a peer dependency on `buffer`. This was causing build errors in apps that did not include the buffer library. (Our codebase included buffer because of vsce.) ### Change Type - [x] `patch` ### Release Notes - [@tldraw/editor] Remove peer dependency on buffer.
