Unexpected behaviour in annotation store when property key has a . in it

[measty]

• Python version: All
• Operating System: All

Description

If a properties dictionary of an annotation has a . in it, some operations of AnnotationStore behave unexpectedly if the operation involves the usage of json_extract

Cause

The root of the issue is in the line:

tiatoolbox/tiatoolbox/annotation/dsl.py

Line 268 in 3cea662

return f"json_extract(properties, {json.dumps(f'$.{self.acc}')})"

In the case of a key which contains a . this ends up being incorrectly parsed. For example, if properties dict has a key 'MSI.status' and you try to do an operation which needs to access that property from the json, it gets parsed into a json_extract function call that instead of accessing a field 'MSI.status' in the JSON, tries to access a subfield 'status' of a field 'MSI' in the JSON
