v0.9.6

Features:

1. Support for :alchemy-escape: attribute entry, which disables all alchemy processing until it is unset (or the end of the file)
2. Disco: New removeMandatoryFallbacks option, which removes fallbacks from fields marked pure mandatory
3. Disco: The Default column is automatically renamed to Fallback
4. Disco: References to data types inside of tables are given a label when normalizeAnchors is enabled

Fixes:

1. Conformance: Comparison expressions can now nest inside logical expressions, e.g. (SomeAttribute < 0) & (SomeOtherAttribute > 0)
2. Disco: Unrecognized columns now appear in their original order when a table's column order is normalized
