Minor release fixing HFS A constant for $^{39}K$ $4S_{1/2}$ state: A constant is now stated in Hz, while before it was erroneously entered in MHz. Bug reported by quantockhills

Bug fix contributed by dehond (Issue 126 , PR 127) :
- when calculating total polarisability, sign of podermotive (dynamic) polarisability was wrong (38ff91029ba8aad4e7440798b895310112291e58)
- docstring explaining order of returned polarisabilities had permuted places of core and podermotive poarisability (882a60f9a6608d8b2175385511658e5d2fe5afb4)

Minor release:

- fixed wrong units in Dynamic polarizability plot (now it is correctly stated, V/m instead of V/cm; 1ece0e160b4ba071545b396cc0517e745d2d175d). Reported by eranreches-weizmann
