[#585] Add checkpoints for Orchard Activation Height (#586) 

* [#585] Add checkpoints for Orchard Activation Height

Closes #585

these checkpoints will be useful for wallets supporting orchard
that had existing orchard activity from activation height on and
after NU5 SDK support is implemented they need to rescan for orchard
funds.

* Add documentation on special checkpoints

To update the checkpoints, see [Checkmate](https://github.com/zcash-hackworks/checkmate).
We generally recommend adding new checkpoints every few weeks. By convention, checkpoints are added in block increments of 10,000 which provides a reasonable tradeoff in terms of number of checkpoints versus performance.
There are two special checkpoints, one for sapling activation and another for orchard activation. These are mentioned because they don't follow the "round 10,000" rule.
* Sapling activation
* Mainnet: 419200
* Testnet: 280000
* Orchard activation
* Mainnet: 1687104
* Testnet: 1842420
