package version numbering change

[Manuel Bouyer <bouyer%antioche.eu.org@localhost>]

Hello,
upstream for geography/opencpn-plugin-watchdog changed, and there is
now properly tagged releases. So I'd like to switch to new upstream
and use release tags. But this would mean that the package version would
go from 20190228 to 2.4.6.

Won't the pkg tools think that 2.4.6 is older than 20190228 ?
If so what's the best way to deal with this ?
