tailwind-merge 1.8.0

Add support for custom separator by @dcastil in https://github.com/dcastil/tailwind-merge/pull/168
Add support for dynamic viewport units in arbitrary lengths by @dcastil in https://github.com/dcastil/tailwind-merge/pull/166
Rename join to twJoin by @dcastil in https://github.com/dcastil/tailwind-merge/pull/161
- I deprecated the join function and renamed it to twJoin to make replacing it via search and replace easier since join is a common function name. You don't need to change anything right now, but if you have some spare time, rename join → twJoin in your code since the join function will be removed in the next major release.
