forked from sheetjs/sheetjs
		
	- parsexmltag and other hot functions now better optimized for v8 - monomorphic functions (different types -> different funcs) - more efficient decode_range implementation when source is trusted - regular expressions cached and simplified without breaking correctness - more efficient utf8 techniques when available - XLSX: large functions broken down into sub-functions (e.g. `parse_ws_xml`) - XLSB: avoid unnecessary binds - XLSB: assume no exotic codepage exists (no one else tries to write XLSB) - demo exposes rABS / worker / transferable options - more tests - jszip updated to 2.3.0 - SSF updated to 0.8.1 - codepage updated to 1.3.1
