When rendering typos, we look up what visual column the typoe starts on
but I mixed a raw byte offset with the offset into a lossy string. This
caused panics when dealing with non-ascii content.
Fixes#258
I didn't count on how `buffer.lines().count()` would handle different
corner cases, like slices with no `\n`, slices with trailing `\n`, etc.
Fixes#259
We want both CLI and config ignores. The question then is what we make
them relative to. I decided to favor CLI with `.`. We'll see how this
works out
Fixes#134
Variant support slows us down by 10-50$. I assume most people will run
with `en` and so most of this overhead is to waste. So instead of
merging vars with dict, let's instead get a quick win by just skipping
vars when we don't need to. If the assumptions behind this change over
time or if there is need for speeding up a specific locale, we can
re-address this.
Before:
```
check_file/Typos/code time: [35.860 us 36.021 us 36.187 us]
thrpt: [8.0117 MiB/s 8.0486 MiB/s 8.0846 MiB/s]
check_file/Typos/corpus time: [26.966 ms 27.215 ms 27.521 ms]
thrpt: [21.127 MiB/s 21.365 MiB/s 21.562 MiB/s]
```
After:
```
check_file/Typos/code time: [33.837 us 33.928 us 34.031 us]
thrpt: [8.5191 MiB/s 8.5452 MiB/s 8.5680 MiB/s]
check_file/Typos/corpus time: [17.521 ms 17.620 ms 17.730 ms]
thrpt: [32.794 MiB/s 32.999 MiB/s 33.184 MiB/s]
```
This puts us inline with `--no-default-features --features dict`
Fixes#253
These were found while running `typos` on Linux and inspecting a
sampling of the results. #249 represents additional changes to make.
There were some identifiers, that looked like hardware registers, that
I'm unsure of what can be done for them.
