Rumble 1.12.0 "Ashoka Tree" beta

• Fixed performance issue when a big for clause follows other small clauses
• Fixed grouping and ordering of floats
• Fixed a bug that prevented grouping with keys of incompatible types when hashcodes collided.
• Experimental (and incomplete) support for XQuery 3.1 syntax (prefix queries with xquery version "3.1"; to activate)
• project() calls are pushed down if the argument is structured (e.g., coming from parquet-file(), etc).
• Performance improvements for round() and abs()
• Variable references ($x) are resolved quicker
• Support for general function types (including their signature) and type checking (including statically)
• When iterating on schema-based data (Parquet, Avro, structured-json-file()...) in a FLWOR expression, some let, for, where, group-by and order-by clauses will be automatically faster if they only involve literals, variable references, object/array lookups, and value comparison (native mapping to Spark SQL)
• Fixed several bugs in switch expressions
• Switch expressions and conditional expressions can handle/forward structured data faster (underlying DataFrames)
