See https://github.com/phinze/homebrew-cask/pull/146#discussion-diff-2872101
for details and the reason for the renaming. To summarise:
`f-lux` is as close as we can get to `f.lux`, and at the same
time we're freeing the spot for another app name `Flux`.

`md5`, `sha1`, `sha256` all take a hexdigest string, e.g:
sha1 'f645e9da45a621415a07a7492c45923b1a1fd4d4'
`no_checksum` takes no argument, and indicates there is no checksum
for this cask. This is *not recommended*, and should only be used for
casks that have no versioned downloads.
`brew cask install` will complain if there is no sum provided (unless
`no_checksum` has been invoked), or if the sums do not match. It will
provide the computed checksum so the cask can be easily amended.
