Compose a stream of CST nodes into a stream of YAML Documents.

Splits an input string into lexical tokens, i.e. smaller strings that are easily identifiable by tokens.tokenType().

Tracks newlines during parsing in order to provide an efficient API for determining the one-indexed { line, col } position for any offset within the input.
