S-Record lexer: add future-proof highlighting for unknown record types

An S4 record for example, which is not defined in the S-Record
specification, will now be highlighted until record end (checksum)
instead of aborting after the "byte count" field. The former behaviour
looked a bit half-baked.

Since the size of the address field is unknown, the address and data
fields are highlighted with the same style in the new state
SCE_SREC_DATA_UNKNOWN. Alternating styles (ODD/EVEN) for readability of
the data field of valid record types are not applied.
