The parse of list-panes output breaks when the screen buffer contains pipe symbol #472
Description
When there are pipe symbols in the screen buffer, the buffer_sample field in the output of "tmux list-session" may contain pipe symbols.
In the "fetch_objs" function of neo.py, the "obj_formatters" use pipe symbols as the delimiter between fields when parsing the output of "tmux list-session", causing an error in the parsing when pipe symbols are present in the buffer_sample field.
This results in failure of all functions that rely on "fetch_objs" such as creating and listing sessions.
