[GNC] Multiple Fiscal Years

[flywire]

With Gnucash V5 current year with a configurable day/month/year was removed
and hard-coded as calendar year.

Alternatives:

   1. Run a GnuCash portable app version since settings are held in the app
   folder -
   https://sourceforge.net/projects/portableapps/files/GnuCash%20Portable/
   2. The easiest and most natural way is to run GnuCash V4  (probably
   from GnuCashPortable_4.13.paf.exe ) and Hack Financial / Fiscal Year in all
