;Procedure:
;  mms_pgs_split_hpca
;
;Purpose:
;  Split hpca elevation bins so that dphi == dtheta.
;  Combined with updates to spectra generation code this should allow
;  the regrid step for FAC spectra to be skipped in mms_part_products.
;   
;Input:
;  data:  Sanitized hpca data structure
;
;Output:
;  output:  New structure with theta bins split in two
;           (2x data points in angle dimension)
