Update license and contact emails

[gowerc]

Hey @kieranjmartin - not sure what email you wanted to use for this now so feel free to push a commit with your preferred choice.

In terms of the change to the license file itself I just ran usethis::use_mit_license() and stuck to what it gave me as default.
