v1.1.0

Minor version adding more json builtins and an improved built-in system.

This change adds some json builtins and also completely refactors the built-in
system to make it more efficient. It also adds some quality of life improvements
to the C++ API. The C API remains stable, but the C++ API exposes additional
methods to make handling outputs of queries a bit easier.

New Features

• json.filter, json.patch, and json.remove are now available
• All built-ins are now accounted for in the built-in system, and those which
  are not supported are explicitly marked as such.
• There is now an Output class, which is returned from the new query_output
  method on Interpreter. It provides methods which are similar to those available
  in the C API for inspecting the output of a query.
• There are now try_get_double, try_get_string, and try_get_bool methods
  which will attempt to get raw C++ types from Node objects.
• The whitelist and blacklist methods in BuiltInsDef provide fine-grained
  control over which built-ins are allowed to be loaded.
• The stmt_limit method on Interpreter provides a time-out mechanism (defined
  as number of statements which the VM is allowed to execute)

Improvements

• The Interpreter object can now be created at almost no cost. A large portion
  of its construction cost was the creation of the BuiltIns lookup structure,
  which now is defined statically in-code.
• The test driver can now run all the tests in the OPA test suite and will skip
  those which use a built-in that is not available in the current implementation.
  This means we do not have to cherry-pick tests anymore, and will pick up
  new tests more cleanly.
• New methods for creating scalar nodes have been added (number, boolean,
  string, null) and the existing scalar methods have been deprecated.

Breaking Changes

• The get_string method, which previously returned the raw string of the Trieste
  node, now tries to get a string from a JSONString node and strips it of its
  quotes (in line with the other get_* methods). The previous functionality is
  available via get_raw_string.

Bug Fixes

• Fuzzer bug with SomeDecl in a NotExpr
• An issue with built-ins not being written to binary bundles
• A unification bug with variables in comprehensions that had the same name as their module
• regopy now performs some additional checks to ensure it is loading the correct
  shared library on all platforms
• Ubuntu 22.04 builds are now working again and the image has been added back to the workflow
• macos/x86_64 image has been added back to the workflow, and shared library builds
  (for the Python and dotnet wrappers)
• Unification bug with masking scopes and variables with comprehensions and every
