Add number inputs for parameters fine-tuning

[0x1a1a1a]

User story: As a user, I want to fine-tune parameters by precise numbers

Context: Currently, when, for example, I am trying to change exposure, a slightest move of a slider leads to change of exposure for several steps. It is hard to choose the correct one, so I have to rely on some internal feeling rather than on numbers

I would love this too as my exposure settings are at the very right end, and it's hard to find the right spot.

In master If you press the label number, you should be able to fine tune it.
I forgot to release the new version, will do ASAP
