Subject: [PATCH] fix wezterm hang by not waiting on cmd response

wezterm does not send a response to the image display command,
so the termpdf.py read command hangs indefinitely, making it
unresponsive.

this fix replaces the call to write_gr_cmd_with_response by a call to
write_gr_cmd, which does not wait for a response.
