Enable filtering auto-application of presets based on metering mode

[frivoal]

Is your feature request related to a problem? Please describe.
The exposure module's "compensate camera exposure" option is often what I want, but almost never what I want when my camera's metering mode is on "Spot".

Describe the solution you'd like
Add a metering mode field, prefilled with %, in the set of fields shown when "auto apply this preset to matching images" is checked, so that I can have two different auto-applying presets, one for spot, one for the rest, with different settings.

Alternatives
I considered creating a profile for that, and applying it manually through the lightroom on relevant images. This works, but is a lot more cumbersome.

You could use a lua-script to do this (and more).

You could catch the darkroom-image-loaded event, check the image metadata and change the module settings to fit the situation. You could also configure a set of presets, then just select the correct one based on the image metadata.

True, I had not considered that possibility.

It does feel like something that should be achievable without scripting, given that auto apply this preset to matching images exists, but in the meanwhile, this is likely an effective workaround.
