Dev/document json ctb file format (#1029)
* docs receiver formats rewrite

* added documentation for all the receiver files, updated release notes, udpated help in commands help for timing, fixed by throwing exception for aa dividy by 0 error caused by not freeing memory (detsize) when switching between 1d and 2d detectors, removed unnecessary 'recevier up' printout, fixed dbit list 64 bit mask error in master json file (was not 64 bit before), fixed bug in reading gotthard1 data (needs to be tested)

* generating commands help and formatting, also fix help for trimen command line

* added ctb frame format documentation, added some links to some commands, added documentation about adding expat-devel in installation for rhel8 gui, fixed some indentation issues that screwed up command line help documentation

* added ctb frame format documentation

* updated documentation about zeromq-devel for <8.0.0 versions

ZMQ: Json Header Format
========================
**Change in field names from slsDetectorPackage v6.x.x to v7.0.0**
* detSpec1 <- bunchId
* detSpec2 <- reserved
* detSpec3 <- debug
* detSpec4 <- roundRNumber
**Format**
