Avalanche Only Supports Old WBTC Bridge

[benleim]

I'm trying to use the SDK with the Avalanche network. When I list the available tokens with getTokens() the only version of WBTC available is 0x408D4cD0ADb7ceBd1F1A1C33A0Ba2098E1295bAB(which is the old WBTC bridge), however, it's clear that the new WBTC.e bridge version (at address 0x50b7545627a5162F82A992c33b87aDc75187B218 is allowed since it appears on the web interface for Paraswap on Avalanche. This seems like a problem with the SDK.
