[Request] API PATCH requests for changing single config values

[morph027]

Is your feature request related to a problem? Please describe.

When changing config via API, we always need to send the complete data structure, even when changing just one single value. This makes it quite hard to integrate into simple tools (e.g. HA automations)

Describe the solution you'd like

Add PATCH methods to API to update single values.

Interesting API feature to have PATCH method for modifying values using a sparse JSON request.

I do not know if this is feasible as we are using the complete JSON and parse the values from it to update them in a batch.
We may have to separate this into individual SET-ter methods for each key value.
Maybe this is too much for the little ESP32 chip ?
