-/**
- * EscapeSequenceParser.
- * This class implements the ANSI/DEC compatible parser described by
- * Paul Williams (https://vt100.net/emu/dec_ansi_parser).
- *
- * To implement custom ANSI compliant escape sequences it is not needed to
- * alter this parser, instead consider registering a custom handler.
- * For non ANSI compliant sequences change the transition table with
- * the optional `transitions` constructor argument and
- * reimplement the `parse` method.
- *
- * This parser is currently hardcoded to operate in ZDM (Zero Default Mode)
- * as suggested by the original parser, thus empty parameters are set to 0.
- * This this is not in line with the latest ECMA-48 specification
- * (ZDM was part of the early specs and got completely removed later on).
- *
- * Other than the original parser from vt100.net this parser supports
- * sub parameters in digital parameters separated by colons. Empty sub parameters
- * are set to -1 (no ZDM for sub parameters).
- *
- * About prefix and intermediate bytes:
- * This parser follows the assumptions of the vt100.net parser with these restrictions:
- * - only one prefix byte is allowed as first parameter byte, byte range 0x3c .. 0x3f
- * - max. two intermediates are respected, byte range 0x20 .. 0x2f
- * Note that this is not in line with ECMA-48 which does not limit either of those.
- * Furthermore ECMA-48 allows the prefix byte range at any param byte position. Currently
- * there are no known sequences that follow the broader definition of the specification.
- *
- * TODO: implement error recovery hook via error handler return values

- * until no promise is returned.

- * Important: With only sync handlers defined, parsing is completely synchronous as well.
- * As soon as an async handler is involved, synchronous parsing is not possible anymore.
- *
