Consider releasing v1.4.0

[ramonsmits]

@EliasOenal could you consider releasing a new version as I've fixed a few issues in the FLEX decoder. I don't know if you follow https://semver.org/ but if you do that would be version 1.4.0

Bugfixes:

• FLEX: Fix edge case where no timestamp prefix was added when running with --timestamp #227
• FLEX: flex_groupmessage moved into for, as it seems that it needs to be determined per page #223

Enhancements:

• Timestamp UTC ISO-8601 mode #224 Non-breaking new arg
• FLEX: Suppress timestamp by passing --flex-no-ts #225 Non-breaking new arg
• FLEX: Estimate the total offset based on the estimated passed full cycles #221 Extra info only with verbose level 2, likely not used by any parsers and can be considers non-breaking

Thanks for fixing the qmake issue. I'll leave it open for a few weeks to wait for further feedback before releasing a new version.

I actually found a small bug in the following:

• FLEX: Estimate the total offset based on the estimated passed full cycles #221

I need to investigate what happens. I also have some other wip branches on my own repo for which I'm considering adding PRs:

My availability in my freetime is a bit limited but I hope to get some done in 2 weeks.
