feature request: multiple p values for detect_lines

[bjarthur]

i'd like to perform harmonic analysis with two different p-values on the same signal. all other parameters the same. it's a huge waste to call utils.detect_lines twice i would think. FFT has to be done twice etc. is there a workaround where i can save partial results? how easy would it be to add a method which input multiple p-values? thanks!

Thanks for your inquiry. I don't currently have the bandwidth to look into this, but I would be happy to review and merge PRs implementing this functionality.
