Refactor artifacts detection + add sturation detection

[samuelgarcia]

@JoeZiminski @oliche

This refactor the artifact detection and blanking

• with a main multi method function : detect_artifact_periods()
• return periods with the new base_period_dtype instead list of list
• SilencedPeriodsRecording also use this new dtype
• DetectArtifactAndSilentPeriodsRecording (replace SilencedArtifactsRecording) do detect and silence at the same
  time to be used in preprocess dict (@chrishalcrow this is for you)
• refactor the method of Pierre based on envleope
• incorporate the method of @oliche and @JoeZiminski to detect saturation

Could also be done in this PR:

• add a margin_ms option in SilentPeriodsRecording to ewxtend the zeroing with a mragin : do we need this ?

To be done in 2 futures PR:

• handle margin and taper on border of SilentPeriod (more tricky that it appear when period is at border...)
• rewrite RemoveArtifactsRecording based on SilencedPeriodsRecording and the new dtype

@samuelgarcia do not forget, in this PR, to change DetectThresholdCrossing(recording, ...) to DetectThresholdCrossing(envelope, ...) in the detec_period_artefacts_by_envelope

Hi @oliche @JoeZiminski
I copy paste and clean a bit your PR #4301 into this one.
Have a look and tell if this is OK.

I think we do not need to scaled traces at each chunk we could only could the unscaled threhold in the init and then we could avoid the costly convertion to float32 or float64.

Also I put the unit in uV to be more SI friendly.

should be envelope here, am I right?
