Same parser c8afea1b (#4494) moved the structured-data extractors to, so
there's one place price text becomes a number. parse_currency() now lists
every caller, and the call sites point back to it.

Change detection post-processors
The concept here is to be able to switch between different domain specific problems to solve.
text_json_diffThe traditional text and JSON comparison handlerrestock_diffOnly cares about detecting if a product looks like it has some text that suggests that it's out of stock, otherwise assumes that it's in stock.
Some suggestions for the future

API schema extension (api.yaml)
A processor can extend the Watch/Tag API schema by placing an api.yaml alongside its __init__.py.
Define a components.schemas.processor_config_<name> entry and it will be merged into WatchBase at startup,
making processor_config_<name> a valid field on all watch create/update API calls.
The fully merged spec is served live at /api/v1/full-spec.
See restock_diff/api.yaml for a working example.
Todo
- Make each processor return a extra list of sub-processed (so you could configure a single processor in different ways)
- move restock_diff to its own pip/github repo
