Fix #79 and remove some hard coded value in tests

[thomasfillon]

As discussed, here is my proposal for fixing #79.

I also change the retun value from log10 to dB (10 log10) and remove some hard coded power value in the corresponding test.

Thx a lot @thomasfillon

can I ask you to add a line in https://github.com/mne-tools/mne-features/blob/master/doc/whats_new.rst to document the fix ?

also you should avoid opening PR from your master branch and use dedicated feature branches

🙏🙏🙏

you're welcome @agramfort ;-)

Done. Is it ok for you ?

also you should avoid opening PR from your master branch and use dedicated feature branches

Sorry for that. Should I delete the PR and move the commits to a new feature branch ?
