PSMList: Use np.fromiter when using a string as accessor (e.g. psm_list["peptidoform"])

[RalfG]

Changed

• When returning a PSM property across the full PSMList (e.g. psm_list["peptidoform"]), np.fromiter is now used instead of np.array. This fixes an issue where if all peptidoforms have the same length, a 3D array of parsed sequences (amino acids and modifications) was be returned instead of an array of Peptidoform object. However, this does mean that all resulting arrays will have the object dtype instead of the previously coerced dtypes. This might lead to issues downstream.
