Should be called in ascending order. Otherwise, call
lineCounter.lineStarts.sort() before calling linePos().
Performs a binary search and returns the 1-indexed { line, col }
position of offset. If line === 0, addNewLine has never been
called or offset is before the first known newline.
Generated using TypeDoc
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.
