Support the byteOffset/charOffset from Region object for replacements

[kgevorkyan]

Sarif supports several options for identify the place of warning/fixes via Region object:

1. By indicating the lines and columns
2. By indicating the byteOffset/charOffset and byteLength/charLength

For now we expect only lines and columns for indicating fix object, but it probably necessary to support byte offsets too

See https://docs.oasis-open.org/sarif/sarif/v2.1.0/os/sarif-v2.1.0-os.html#_Toc34317889

Under this issue we probably can introduce introduce our own model here. And make differences on class level: ReplacementByLine, ReplacementByOffset and etc., as suggested by @nulls
