Handling of \n character in MIME::Types.type_for

[ooooooo-q]

I have found a pattern inMIME::Types.type_for where the decision is wrong if there is a \n character.

❯ bundle exec irb
irb(main):001:0> require 'mime-types'
=> true # mime-types (3.5.0)

irb(main):002:0> MIME::Types.type_for("test.pdf")
=> [#<MIME::Type: application/pdf>]

irb(main):003:0> MIME::Types.type_for("test.txt\n.pdf")
=> [#<MIME::Type: text/plain>]  # <- detected as text, not pdf

irb(main):004:0> MIME::Types.type_for("test.txt\r.pdf")
=> [#<MIME::Type: application/pdf>]
irb(main):005:0> MIME::Types.type_for("test.txt\0.pdf")
=> [#<MIME::Type: application/pdf>]
