feat: implement timer module (#118)

Implement a timer module that takes a commandline argument, the number of seconds the last job took to complete, and displays it if appropriate.

Alters shell initialization files to compute this number using date +%s where needed.

Adds a config section to configure minimum amount of time before timer is shown (default is 2s)
