Soft and hard clipped bases
Hi, I just wanted to double-check that `mosdepth` does not include soft and hard clipped bases in calculating coverage depth. I.e., if bases are clipped in the alignment, they do not add to coverage depth. I noticed [here](https://github.com/brentp/mosdepth/blob/388d2e0d5739b894ed9e0e82cfd771d710cf4bb3/CHANGES.md?plain=1#L67) that `mosdepth` is said to "consider" soft and hard-clipped bases, but I was unsure how to interpret that. 

Thanks!
