Support for non-18 decimal custom gas tokens

This release adds support for non-18 decimal custom gas tokens. Added by brtkx, spsjvc and chrstph-dvx in https://github.com/OffchainLabs/arbitrum-sdk/pull/445, https://github.com/OffchainLabs/arbitrum-sdk/pull/530 and https://github.com/OffchainLabs/arbitrum-sdk/pull/539.

The necessary scaling is done in the background for you. However, if you need to do any scaling yourself (e.g. for approvals), we've provided the following utilities - `scaleFrom18DecimalsToNativeTokenDecimals` and `scaleFromNativeTokenDecimalsTo18Decimals`.

Other

* Added `AdminErc20Bridger` to exports (spsjvc in https://github.com/OffchainLabs/arbitrum-sdk/pull/548)
