                                             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
