NTRIP UDP: Add cli option to re-estimate rx clock error
Vis: modify visualisation tools to accept either satlogs or residlogs depending on cli options
Log: add a script that does no calculations, only records synchonized port and NTRIP data

Each port and NTRIP server is optional. It's all set up in a format suitable for later
parsing (ntrip work to come on that front..)
