improve span highlighting (#4480)

At first I thought simply changing the regex might help, but then I
found more and more differences between Mastodon and Tusky, so I decided
to reimplement the thing. I added 74 testcases that I all compared to
Mastodon to make sure they are correct.

On an Fairphone 4 the new implementation is faster, on an Samsung Galaxy
Tab S3 slower.

Testcases for the benchmark:
```
test of a status with #one hashtag http
```
```
test
http:// #hashtag https://connyduck.at/
http://example.org
this is a #test
and this is a @mention@test.com @test @test@test456@test.com
```
```
@mention@test.social Just your ordinary mention with a hashtag
#test
```
```
@mention@test.social Just your ordinary mention with a url
https://riot.im/app/#/room/#Tusky:matrix.org
```
