Hi @robert-zaremba . Thank you for this change. Would you be able to please split this PR up into smaller components to ease and speed up the review process?

We could probably start by splitting up types and osmoutils into another PR. What do you think?

[robert-zaremba]

Here is the spec: https://github.com/osmosis-labs/osmosis/pull/2605

[robert-zaremba]

@p0mvn OK - I will remove other files and leave types and osmoutils in this PR.

From the latest updates, streamswap is not planned to be pursued as a Go module so I'm going to close this for now. Thank you @robert-zaremba and please let me know if any concerns

[robert-zaremba]

All good, thanks @p0mvn
