Referral mints

[vikiival]

Context

We would like a way for people to obtain a small reward for referring someone to mint.

Task

1. create a new function called function mintWithReferral(address to, uint256 quantity, address referrer) public payable (basically functionaliy of safeBachMint)
2. with the payment splitter enabled - the referral amount will be deducted from the owner's part (therefore _receiver's part is untouched)
3. referral amount is equal to royalty price - that is calculated with royaltyInfo
4. if referrer is equal to _receiver || address(0) referral bounty cannot be applied (do not throw error just code should ignore that)
5. if royaltyInfo also returns 0 the referral bounty cannot be applied.
6. Extend tests to ensure the stuff works
