Testcard interlaced content

[TheSashmo]

Anything I do, to try and generate interlaced content for test card results in a crash. Tested with release and continuous build.

./UltraGrid-continuous-x86_64.AppImage -t testcard:1920:1080:59.94:v210:i (FAILS) ./UltraGrid-continuous-x86_64.AppImage -t testcard:1920:1080:59.94:v210:pattern=interlaced:i (FAILS) ./UltraGrid-continuous-x86_64.AppImage -t testcard:1920:1080:59.94:v210 (WORKS, but in progressive)

Seems like this is already fixed in 6ad63dc

So the issues is the placement of the i in the command. Got it.

The help is incorrect.

testcard options: -t testcard[:size=x][:fps=][:codec=][:file=][:p][:s=x][:i|:sf][:still][:pattern=] | -t testcard:help

The help is incorrect.

Well, not entirely, it was the old syntax that meanwhile somehow ceased to work (also because we didn't use it, since 'i' can be used in fps). But it was also fixed meanwhile.

I've slightly modified the help to make clean that fps option accepts 'i' suffix.
