vt: bug: state machine: csi entry: handle 0x3a/0x3b correctly

Browse source 
0x3a/0x3b are ':' and ';'. These should not only switch to the 'csi
param' state, but also be parsed as a parameter.

This fixes an issue where a multi-parameter escape with the first
parameter omitted was parsed incorrectly - as if the first parameter
wasn't there.

I.e. "\e[;123r" was parsed as "\e[123r"
