Fix Fixnum, Bignum deprecations in Ruby 2.4 (#33)

Fixnum and Bignum have been deprecated in Ruby 2.4. In any case, both of
these classes are subclasses of Integer, so using just Integer in the
case statements is sufficient. Remove references to Fixnum and Bignum to
silence the deprecations warnings.
