Whoa there, partner! 🌵🤠 We wrangled some duplicated code in your PR:

• modules/adrelevantisBidAdapter.js has 21 duplicated lines with modules/winrBidAdapter.js
• modules/adrelevantisBidAdapter.js has 16 duplicated lines with modules/craftBidAdapter.js
• modules/adrelevantisBidAdapter.js has 26 duplicated lines with modules/pixfutureBidAdapter.js
• modules/adrelevantisBidAdapter.js has 23 duplicated lines with modules/pixfutureBidAdapter.js

Reducing code duplication by importing common functions from a library not only makes our code cleaner but also easier to maintain. Please move the common code from both files into a library and import it in each. We hate that we have to mention this, however, commits designed to hide from this utility by renaming variables or reordering an object are poor conduct. We will not look upon them kindly! Keep up the great work! 🚀

t's difficult to fix the duplicate code in the adrelevantisBidAdapter. I'll give up on it.
