v1.0.0

Add raw-line regex parsing from logTypeConfig

Plain-text log types are now parsed by the plugin using the Log Type's
regex/dateRegex (Fluentd plugin parity): named-capture extraction,
stack-trace continuation stitching, and a 30s hold timer for the last
line. Also: masking/hashing/derived/filter/ignored_fields pipeline,
README corrections (Log Source: Log Collectors), and raw-log test files.
