Buffer Capture
The screen's text buffer can be captured via VT sequence suitable for shell integration, such as fzf.
Request Syntax
Pl is 1 if the lines are to be counted logically and 0 if the lines are to be counted visually.
A logical line is may be a wrapped line that spans more than one visual line, whereas a visual line always maps to exactly one line on the screen.
The parameter Pr is the number of lines to be captured.
Response Syntax
The response is may span multiple PM sequences.
The reply will always end with a PM message with an empty <data> block, denoting the end of the reply.
Each <data> chunk will be UTF-8 encoded of the text lines to be captured. Each line will be delimited
by a newline escape sequenced (LF).
