### GlyphTable.ChainedCoverageSequenceRule

    public GlyphTable.ChainedCoverageSequenceRule(GlyphTable.RuleLookup[] lookups,
                                                  int inputSequenceLength,
                                                  GlyphCoverageTable[] coverages,
                                                  GlyphCoverageTable[] backtrackCoverages,
                                                  GlyphCoverageTable[] lookaheadCoverages)

  Instantiate a ChainedCoverageSequenceRule.

  Parameters:
    `lookups` - the rule's lookups
    `inputSequenceLength` - number of glyphs constituting input sequence (to be consumed)
    `coverages` - the rule's input glyph class sequence to match, starting with first glyph in sequence
    `backtrackCoverages` - the rule's backtrack glyph class sequence to match, starting with first glyph in sequence
    `lookaheadCoverages` - the rule's lookahead glyph class sequence to match, starting with first glyph in sequence
