Switch to mini_mime gem from mime-types

[rocket-turtle]

First of all thank you for continuing with paperclip. :)

Are there any planes to switch to mini_mime?

mini_mime is a more performant replacement for the mime-types gem. It uses the same database, but loads it in a more efficient manner, improving the number of allocations, memory, and speed.
The mail gem, which is a core component of Rails, has already switched to it.

Some more switches I could find:

capybara
teamcapybara/capybara#1884

rest-client
rest-client/rest-client#557

Using bumbler to measure the boot time, I was also very suprised that kt-paperclip too 4x as long as Rails:

91 of 115 gems required
Slow requires:
    127.06  rails
    147.24  country_select
    156.98  mime-types
    694.53  kt-paperclip

I guess mime-types is one of the reasons?

EDIT: nevermind, I've updated to version 7+ and mimemagic/mime-types was pulled to, now it is below the 100ms threshold.
