Mix diagnosis guides

Every guide starts from a symptom and ends with a measurement.

Each guide names the frequency range behind the problem and the EQ move that fixes it. If you would rather not guess which one applies to your track, upload it and the analysis tells you which of these are actually present, with severity grades and the numbers behind each finding.
