Add info to statusline when a session is active/tracked

[kiryph]

Other plugins such as vim-obsession by tpope provide a statusline string to indicate that currently a session is active.

Could we add something similar to fzf-session.vim as well?

(Whoops, lost this one!)

This is a good idea. PRs definitely welcome, or if I get some time to investigate how to do this, I'll take a look. Can't promise anything sadly...
