Fixes

• Fixed comparing strings with <, <=, > and >= in boolean expressions ({% if %} and {% unless %}). Previously we were raising a LiquidTypeError, now we return the result of comparing two string by their lexicographical order. See #141.

Features

• Added CachingChoiceLoader, a template loader that chooses between a list of template loaders and caches parsed templates in memory. (docs, source)
• Added PackageLoader, a template loader that reads templates from Python packages. (docs, source)

Dependencies

• Python Liquid now depends on importlib-resources >= 5.10. This is that backport of importlib.resources from Python's standard library. We use it in PackageLoader.
