Modify the way that the constants for conversion to mV and pC are defined
so that it will compile with and without C11.

Include methods for FADC conversions and apply to non-raw data objects in THcRawAdcHit

Add raw pulse time data object to Cherenkov detector classes

Add raw pulse time data object to shower detector classes

Add raw pulse time data object to hodoscope detector class

Add method
GetF250_PeakPedestalRatio() {return fPeakPedestalRatio;};

so that a detector class can calculate the pedestal that was used
in determining the pedestal subtracted FADC Pulse Integral.

This is useful if the detector class wants to set a threshold
above the pedestal.

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.

- renamed internal variables to more vocal names
- added boundary checks to new Get methods
- removed obsolete get methods
- added new get methods
- updated documentation accordingly

Added channel to time coefficients to the Adc and Tdc raw hit classes.

This makes the code nicer and with less duplication in logic.

Along with that I had to correct all the call sites to the RawHodoHit in all the
classes that use it.

Added new class THcRawTdcHit.
RawShowerHit update.

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.

The new class THcRawAdcHit is meant to represent the raw ADC hits. The
logic with dealing with ADCs has become quite complex now and it would
have to be multiplicated across all detectors that have ADC
channels. While this by itself is not such a big problem, fixing
possible bugs in multiple places is.

I also redesigned the THcRawShowerHit class to use the new
THcRawAdcHit. The redesign was due anyway, so I took the opportunity.

I also had to modify THcShowerArray and THcShowerPlane. They still
need some work to use the the new flash 250 data, but changes were
necessary anyway.

Minor fix 01.
