A large number of changes to the HATRA '21 position paper. We've abandoned the 4pp limit, which allows us to add more detail to some sections, and use more appropriate wording throughout the paper. A rough changelog:
* Numerous wording tweaks
* Removed `\cite{???}`
* Added type inference section
* Introduction beefed up
* Abstract slightly tweaked
