Propose new decay rate

[mctrivia]

DigiByte current block rewards end on block 40265288 with 90.29 DGB/block this is a huge drop to 0 and probably way to close to the current date for tx fees to take over.

I propose we change the decay rate of the rewards at block 12993200 from 0.98884 to 0.98652 this will make almost no difference to rewards over the next 5 years but will stretch the rewards phase to block 116731970 with a 0.16 DGB/block reward.

I have written a block reward simulator so you can easily double check my math available at https://github.com/mctrivia/dgb_reward_simulator

I support this proposal.

Having commented on this on the other places, I just want to reiterate my thanks to @mctrivia for picking this up and running with it, and thanks too for correcting my also slightly off math 😅
On a personal level I'm of two minds about pushing out the final emissions date, however this 100% needs to be addressed sooner rather than later, I'm in full agreement with you there. This can should not be kicked down the road and no matter which route it's taken it should be resolved in DigiByte version 8.

This PR will be closed in favor of some new PRs. Please follow #20.

The subsidy parameter will be used if I can confirm it is appropriate.

Thank you @mctrivia
