Support Sharing calculation

[ForwardFeed]

in reference to #499
I haven't fully tested it however as I don't know too much how should I test it.
in todofix there is this bug with Dynamax and non-full HP situation.

@thejetou opinions? I'm sure a lot of people would like this feature.

After some testing, it does seem to works for abomasnow but fails to work if you try sharing a calc with a different pokemon. I'll see if I can figure out whats going on and hopefully we can merge this.

[AustinXII]

Oh I see, it only doesn't work if the Pokémon has more than one form

[AustinXII]

Also the set should only be shown in the same generation the damage calc was made in. Currently if you shared a damage calc and the person uses the link, that set would be shown in all generations.

When I did the code a while back ago it was supposed to redirect the receiver gen to the sender gen. this PR is likely not up to date of the current codebase on many points.

@ForwardFeed I would love to add this if you’d take a jab at updating this PR now that I’m back.

I'm sorry I'll probably not work on the smogon calc in the future. I've made this PR 9 months ago, In between I have made my own fork where i changed a lot of code that i don't remember well the codebase of the smogon calc and currently If I'm again working on a calc I would want to make my own nuzlocke specialized calc would I have time and value for that.

@ForwardFeed no problem at all. We appreciate the PR, I’m sorry for the ghosting and no response.
