[API]: Enhance estimateFee to cope with being a maker

[JonRay15]

API Overview

Currently the estimateFee API always assumes you are the TAKER and provides output based on that.

it would be great if it behaved differently if you put type:"TYPE_LIMIT".

In that case we could treat the order as if it is NOT the aggressor and return the fees received by you as the maker.

So presumably everything would be zero except for:

• makerFee
• highVolumeMakerFee

And we would want to look up the correct value for highVolumeMakerFee based on the party provided.
