Add hand-powered battery charger

Summary

SUMMARY: Content "Add hand-powered battery charger"

Purpose of change

With the new-found proliferation of rechargeable batteries, players are somewhat stymied by the lack of options for putting more charge into the batteries. Currently the only available option in-game is the vehicle-mounted Recharging Station.

Partially addresses #30256 (I still think we need additional options, so that issue should probably not be closed yet)

Describe the solution

Added a hand-crank charger item, an iuse activity, and all the attendant c++ and json plumbing to make it so.

My research suggested that hand-crank charger outputs range from 2 watt (very common and easily verified) to 10 watt (claims I could only find from specific manufacturers, with little outside corroboration). I ultimately opted to aim for just under 7 watts of throughput to get 25 kJ / hour.

At this rate one battery charge is produced every 2.4 minutes (24 turns under the current 6-second turn model), and with the fatigue rate available to me, it looks like a 100% fully rested (zero fatigue) player hits 'dead tired' after about 10.5 hours of constant cranking, yielding ~259 charge. This means a player can come reasonably close to filling a medium battery cell in a single day's labor. The right comestibles could extend this.

Is this worthwhile? Probably not outside of emergencies. But it's an option that was missing that we reasonably should have had.

I'm not 100% sure on the recipe requirements. I was aiming for "substantially easier than the vehicle charger, but not trivial". Feedback welcome.

For worldgen, I added this to supplies_electronics, tools_common, tools_electronics, and tools_survival. I'm not very confident on the weights I used there, either.

Basically, if there's any changes someone wants to see on anything except the charge rate (which I'm fairly certain of), I'd be happy to accommodate.

Describe alternatives you've considered

I had originally planning on making a charger that would funnel power from battery magazine A into battery magazine B, but I decided this would be easier to do. I'd still like to get that done at some point.

I considered adding a morale penalty or kcal consumption to this activity, but I decided I just don't have the confidence to work out what those should be.

You can change this to

	if( calendar::once_every( 144_seconds ) ) {

I swear I tried that and got an error. Let me try again.

[esotericist]

src/activity_handlers.cpp:2038:34: error: no matching literal operator for call to 'operator""_seconds' with argument of type 'unsigned long long' or 'const char *', and no matching literal operator template
    if( calendar::once_every( 144_seconds ) ) {
                                 ^

Both VS Code and clang say this is not legal.

That problem is the origin of the comment immediately above the line, btw.

[Night-Pryanik]

Well, we could circumvent that by using something like 2_minutes.

Seems like the right balance of useful and annoying-to-use. I'm for it.
