v0.7.2

• When contracting with slices and strip_exponent enabled, each slice result is returned with the exponent separately, rather than matching the first, these are are now combined in gather_slices.
• If check_zero=True, strip_exponent=True, and a zero slice is encountered, the returned exponent will now be float('-inf') rather than 0.0 for compatbility with the above.
