Subject: Implement proof-of-work

Using blacke2s: https://docs.rs/blake2/0.9.1/blake2/
Using this guy's hash checker https://gist.github.com/gkbrk/2e4835e3a17b3fb6e1e7

blacke2s with 5 bits 0 can mine a block between 20 seconds to 359 during
my tests, hope it'll be fun

 ## Proof-of-work
-- [ ] pick a block proposal scheme (= pick hash function) [list of hash functions](https://en.bitcoinwiki.org/wiki/List_of_hash_functions)
-- [ ] check the nonce for incoming blocks
 
 ## Authentication
 - [X] pick a user authentication scheme = [JWT](https://tools.ietf.org/html/rfc7519) Seems perfect

 ## Done & Brag
 - [x] Switch to RwLock (parking_lot) (done at 2021-04-07 03:43, two possible schemes to represent inner Db (ledger) in code)
 - [x] We need our own representation of students and their grades, "there is no blockchain" (done at 2021-04-12 00:05)
