## PR-Codex overview
### Focus of the PR:
This PR focuses on adding new ERC20 tokens and gauge configurations for
the Binance Smart Chain (BSC) network.

### Detailed summary:
- Added a new ERC20 token `rBNB` with its contract address, decimals,
symbol, name, and website link.
- Added new gauge configurations for different token pairs on the BSC
network, including `mPENDLE-PENDLE`, `mDLP-DLP`, and `rBNB-BNB`.
- Each gauge configuration includes a unique ID (`gid`), pair name,
contract address, chain ID, gauge type, and token addresses.
- The `rBNB-BNB` gauge also includes the addresses of the two tokens
involved, as well as the fee tier.
