Hash#assert_valid_keys

Validate all keys in a hash match <tt>*valid_keys</tt>, raising ArgumentError
on a mismatch. Note that keys are NOT treated indifferently, meaning if you
use strings for keys but assert symbols as keys, this will fail.

  { name: 'Rob', years: '28' }.assert_valid_keys(:name, :age) # => raises "ArgumentError: Unknown key: :years. Valid keys are: :name, :age"
  { name: 'Rob', age: '28' }.assert_valid_keys('name', 'age') # => raises "ArgumentError: Unknown key: :name. Valid keys are: 'name', 'age'"
  { name: 'Rob', age: '28' }.assert_valid_keys(:name, :age)   # => passes, raises nothing
