docs: configuration for testing

[MASDXI]

the network block time is 12 seconds,

deploy with LightweightERC20EXPBase as the base token contract

set block time to 657435000
set frame size 1 or 2
set development flag to true

ERC20EXPBase(0, 657435000, 1 or 2, true)

result blocksPerEra is 48 blocksPerSlot is 12 or 24
This means tokens will expire every 12 blocks (for frame size 1) or 24 blocks (for frame size 2).

It's needs to bypass the block time check with the dev mode flag useful when need custom expiration period
