Update `binance` spot pairs with `amendAllowed`

As per API updates,
https://developers.binance.com/docs/binance-spot-api-docs
https://developers.binance.com/docs/binance-spot-api-docs/faqs/order_amend_keep_priority

I also slightly tweaked the filed mismatch exception note to include the
`repr(pair_type)` so the dev can know which pair types should be
changed.
