PSE125 holds information about setting of F250 modules. Now this
information is used to set `fNPedestalSamples` and `fNPeakSamples`
parameters of `THcRawAdcHit`.

This is done through `THcHitList`, since it has information about
which crate and module each channel is in. Currently, the information
is set for each event, because of the hitlist and analyzer design.

I added the neccessary support for these changes to all raw hit
classes.

`THcTrigRawHit` now uses raw ADC and TDC classes.
Added new leaves to the `THcTrigDet` Root output.

The f250 modules can produce at most 511 samples (9 bit) so it seemed reasonable to increase
the maximum number of samples in the raw hits to this value.

Modified THcTrigRawHit.
Modified THcTrigDet.
Updated documentation.
