Before this change we were reading input from stdin using the terminal
in the default line mode which has a limit of 4095 characters.
The typical culprit was onedrive tokens (which are very long) giving the error
Couldn't decode response: invalid character 'e' looking for beginning of value
This change swaps over to use the github.com/peterh/liner read line
library which does not have that limitation and also enables more
sensible cursor editing.
