Reduced memory requirement for filterPeaks; closes #71

[sgibb]

Dear @paoloinglese,

thanks again for your great contribution in PR #71.
Unfortunately I can't modify your PR. That's why I closed #71 it and add this new one.

I did just a few minor changes (e.g. replacing the lapply(l, above.min) with tabulate).
If you are happy with this changes I will merge it into the main branch.

Best wishes,

Sebastian

BTW: will this make #70 obsolete for you?
