ACP-103: Finalize parameterization

[StephenButtolph]

Why this should be merged

This PR finalizes the ACP-103 parametrization.

How this works

Capacity             = 1_000_000 gas
CapacityTimeToRefill = 10s

MaxGasPerSecond      = Capacity / CapacityTimeToRefill = 100_000 gas/second
TargetGasPerSecond   = MaxGasPerSecond / 2             =  50_000 gas/second

MaxBlockBytes   = 1_000_000 bytes
MaxBlockReads   =     1_000 reads
MaxBlockWrites  =     1_000 writes
MaxBlockCompute =   250_000 micro-seconds

GasPerByte        = Capacity / MaxBlockBytes   =     1 gas/byte
GasPerDBRead      = Capacity / MaxBlockReads   = 1_000 gas/read
GasPerDBWrite     = Capacity / MaxBlockWrites  = 1_000 gas/write
GasPerComputeTime = Capacity / MaxBlockCompute =     4 gas/micro-second
