An array of creators and their share of the royalties. This array is limited to 5 creators.
Note that, because the Creators field is an array of variable length, we cannot guarantee the
byte position of any field that follows (Notice the tilde ~ in the fields below). Each creator
contains the following fields.
The creator's shares of the royalties in percentage (1 byte) — i.e. 55 means 55%. Similarly to
the Seller Fee Basis Points field, this is used by marketplaces but not enforced by the Token
Metadata program.
