Test failure with GHC 9.14 #5

Hi,
trying to build paramtree 0.1.2 with GHC 9.14 on Arch fails during testing with the error "Test output was different from 'tests/paramtree.golden'". Looking at the mentioned file, the difference seems to be in the header.

Output with GHC 9.14:

Tests
  paramtree: FAIL (0.04s)
    Test output was different from 'tests/paramtree.golden'. It was:
    �7�[10000;10000H�[6n�8paramtree
      1 Int #1
        False Bool/'a' Char
          1337 Int #2:   OK
          42 Int #2:     OK
        True Bool
[...]

It seems like there is some additional formatting going on before the "paramtree" header.
