Disable rectangle tool

* Use kcl_input! macro

These two lines are equivalent:
`kcl_input!("foo")`
`include_str!("inputs/foo.kcl")`

Simplifies the tests.

* Move more KCL test programs into their own files

* Move twenty-twenty asserts into their own function

* Move more asserts into 'assert_out'
