Some methods should be locked while the sale is active

[cleanunicorn]

Description

The owner has permission to change some important parameters while the sale is active:

• setMaxMintPerAddress
• ownerMint
• setMintPrice
• setMerkleRoot

The parameters controlled by these methods are very important for the users.

A few examples of why these methods should be inactive while the sale is happening:

• owner can change the token price
• owner can change the merkle root
• owner can change the token limit sale per address

The users assume the contract they are interacting with is safe. This includes coding bugs and centralization issues, such as the owner being able to change the price mid-auction or changing the token limit sale.

Recommendation

Do not allow the methods to be called while the sale is active.
