New formal arguments: step_ppss.do_step_config(…, acq_time=1, **kwargs)
New default: step_config.ppss(…, acq_time=6, …)
The acq_time parameter tells the FPGA how many additional ADC cycles
(1µs) to wait before a digitization from the idef-x output is accepted.
The old default acq_time=1 gives a total of 2µs settling time for the
idef-x analog output. acq_time=6 extends the settling time to 7µs.
There are two digitizations per trigger. The new default adds 10µs to
the total readout time.
The readout time shall be extended to test, in orbit, if that expels the
ghosts from the haunted channels.
Extending the readout time by increasing acq_time has the least impact
on the calibration and morphology of the signal in the presence of
pileup.
The new parameter page is is the base address of the config in EEPROM.
The ID text goes to EEPROM_base + page + 0x40.
The index table goes to EEPOM_base + page + 0x80.
The data goes to EEPOM_base + page + 0x100.
The default is page=0, reproducing the old bahaviour.
hetept/config.py:
Increment version to v0009. Add a function for generating PHA cadence patches.

Increasing ept_2dhist_cutoff from 125keV to 1MeV.
The EPT PHA buffer for penetrating particles is mainly filled with MIPs.
Increasing the cutoff to 1MeV should filter most MIPs and increase the number
of PHA words from non-relativistic particles.

New data products for EPT stopping particles:
Introducing NO_EPT_mag and NO_EPT_foil, two data products with fully symmetrical binning for INT and MAG with 77 energy channels covering the full range of the l3histogram above 25 keV at 1s/5s cadence in CLOSE/FAR mode.
Introducing B1_EPT_mag, a burst mode data product that can be used together with NO_EPT_mag to double the energy resolution up to 1.6MeV.
All other EPT data products for stopping particles have been removed.

PHA data for 2D EPT events is spammed by relativistic protons.
This change adds an itot limit for inclusion into the EPD-2D PHA buffer.
An extra instruction is required to implement this limit. An upload of
the complete L3 trigger is required for deployment.

hetept/config.py: Increment version to v8. In v8 the HK_ANA candence is changed back from 600s to 60s. HET ABnC stopping proton PHA buffer reverted to status of r8033.
