WIP: Add SWT, requires PR #132

[ssailer]

Changelog:

• add fc-stream-processor library code to Orca
• remove some readout-fc250b cli flags from internal cli composition, config storage and GUI input. These are readout-fc250b pulse reconstruction but not FlashCam hardware, like filterType and flatTopTime.
• remove commandline flags which are intended for specialized trigger hardware, which is very unlikely to be used.
• fix influx command timestamps and send card/slot/chan tags separately for event fpga and energy values.
• fix gui locking in (global) trigger model
• add software trigger to the FlashCamListenerModel:
  • swt lib fsp wraps fcio library for efficieny. This allows making usage of the software trigger optional via a global check (per listener)
  • save swt config parameters to config
  • expose input of swt paramters via ADCCard GUI for per-channel values and Readout GUI for global settings
  • expose performance parameters/monitoring in ReadoutModel similar to standard stream processing

This pull request is based on PR#132 and should only be merged after. Especially the GUI updates would probably create conflicts.

Some conversation should happen as well about certain parts of the processing, and how to move forward with data stream updates. This would remove commented sections of the code from this PR to an implementation branch.
