Reduce redundant escape codes #99

Currently, tere outputs a lot of redundant escape codes. When starting tere in a folder containing two subfolders bar and foo, the following escape codes are printed:

^[[?25l^M
^[[1;1H^[[2K^[[1;1H^M
^[[0m^[[1m^[[4m/tmp/xxxxxxxxxx^[[0m^M
^[[1;1H^[[2K^[[1;1H^M

(Printed using cat -v tests/expected-output-basic.txt, newlines added for clarity.)

Some issues to be fixed in this PR:

Lot of unnecessary ^[[0m (reset attributes) commands
The attributes are repeated for each character. For example, when printing foo, it should be
^[[24m^[[49m^[[39mfoo instead of
```
^[[24m^[[49m^[[39mf^M
^[[24m^[[49m^[[39mo^M
^[[24m^[[49m^[[39mo^M
```
