Weird/incorrect behaviour when checking local links

[fenuks]

I'm using lychee 0.15.1 on Arch Linux.

Here is an example markdown document:

# Incorrect or strange behaviour
## Links not being checked
- [ ] [Test1](~/Downloads/not checked because of space)
- [ ] [Test3](/home/nonsense/not-checked2-absolute-path)

## Links checking not working because of tilde
- [Test4](~/incorrect-check)
<!-- ✗ [ERR] file:///home/me/Documents/~/incorrect-check | Failed: Cannot find file -->

# Links checked correctly
- [Test5](./correct-check)
<!-- ✗ [ERR] file:///home/me/Documents/correct-check | Failed: Cannot find file -->

It seems that lychee skips links with absolute path or spaces, and it doesn't handle links with ~ as absolute links.
