Please update dependencies

[j-adamczyk]

Due to clean-text using Pandas 1.* and emoji 1.*, I can't update my dependencies. It shouldn't require any code changes in clean-text, as far as I can tell, just change in requirements.

Addressed in the latest release. Dependency constraints have been updated: emoji >=1.0.0,<3.0.0 and pandas >=1.0.0,<3.0.0. The code has also been updated to work with emoji 2.x (EMOJI_DATA instead of UNICODE_EMOJI, removed deprecated use_aliases parameter).
