Change package name to avoid name clash with unrelated CRAN package

[gvelasq]

An unrelated package also called lookup has just been released on CRAN. Running update.packages() or RStudio's Update packages... will give a prompt to overwrite this GitHub package. It seems that this is a popular GitHub-only package so I imagine others will have this issue.

Here are three suggestions for a new package name: readthis, readsrc, and luke (the latter based on the meme in the README).

CC'ing @maelle since she showed interest in a pkgdown site in #41. Related issue: #42.
