FrozenError when using tp

[nikgregory]

• ruby 2.7.4 via RVM
• gem install table_print 1.5.7 and pry 0.14.1

pry
[1] pry(main)> require 'table_print'
=> true
[2] pry(main)> foo = {'bar'=> 'baz', 'bat'=> 'bit'}
=> {"bar"=>"baz", "bat"=>"bit"}
[3] pry(main)> tp foo
FrozenError: can't modify frozen String: "bar"
from /Users/nik/.rvm/gems/ruby-2.7.4/gems/table_print-1.5.7/lib/table_print/fingerprinter.rb:44:in `clear'

Perhaps I am doing something incorrectly?

table_print is designed to print an array of hashes, so should be:

foo = [{'bar'=> 'baz', 'bat'=> 'bit'}]
