Deregister plugins with missing dependencies

[dachengx]

replica of #85

After AxFoundation/strax#775, some targets are deregistered when it is provided by a replaced plugin. Like after

fuse/fuse/context.py

Line 92 in 28a2e85

for plugin in pmt_and_daq_plugins:

, the raw_records_aqmon will be no longer registered, so that the aqmon_hits and all plugins depend on aqmon_hits can not find there dependencies and an error will raise.

This PR deregisters the plugins without dependencies to fix the error.

But note the configs are still not deleted so you will see something like:

WARNING:strax:Option hit_min_amplitude_nv not taken by any registered plugin

after deregistering those unnecessary plugins.

Thanks for re-opening the PR @dachengx. For me this looks fine!
