Added a theorem that states if a set has positive s-dimensional Hausdorff measure, then it has an accumulation point, along with necessary proofs.

feat(MeasureTheory/Measure/Hausdorff): proved: If s>0 and a set EโŠ‚R^n has positive s-dimensional Hausdorff measure, then there exists a point xโˆˆR^n that is an accumulation point of P(E).

All lemmas and theorems:

exists_accPt_of_pos_hausdorffMeasure

Harmonic's Aristotle gave the initial version of the proof.
