LGTM

I have a feeling this TODO might now be useful to implement and then create a CLI flag for, maybe in a follow up issue

Worked well on a local devnet, will scale up and do some rounds on 32GiB sectors with real data.

Deal sector in sector 1:

lotus-miner sectors list
ID   State    OnChain  Active  Expiration                     Deals  DealWeight  VerifiedPower  
0    Proving  YES      YES     1550097 (in 10 weeks 8 hours)  CC                                
1    Proving  YES      YES     1550097 (in 10 weeks 8 hours)  1      2KiB        18KiB      

No unsealed sector:

lotus-miner storage find 1
In 94f8a49e-1208-442d-b960-9c6fca5ec2a0 (Sealed, Cache)
        Sealing: true; Storage: true
        Local (/root/.lotus-miner-local-net)
        URL: http://127.0.0.1:2345/remote/sealed/s-t01000-2

Then execute: lotus-miner sectors unseal 1

lotus-miner storage find 1
In 94f8a49e-1208-442d-b960-9c6fca5ec2a0 (Unsealed)
        Sealing: true; Storage: true
        Local (/root/.lotus-miner-local-net)
        URL: http://127.0.0.1:2345/remote/unsealed/s-t01000-1
In cefc9816-79fc-4884-84d4-eb1b6cedf697 (Sealed, Cache)
        Sealing: false; Storage: false
        Local (/root/.genesis-sectors)

@ZenGround0 I think this requires a bit of thought as to where we'd want to move the unsealed sector too. Don't wanna gate this PR on that
