fix: minimal ts erros for group-ui imports

[ryanchristo]

This pull request includes minimal typescript fixes needed for the amino signing support solution in groups-ui:

• feat: add amino signing support groups-ui#69

This is only a temporary fix and generating the code will overwrite the changes here but this would unblock us from adding amino signing support to the groups-ui.

[ryanchristo]

This is not the ideal solution but I think we should tag another alpha version with the changes here so that we can at least get the groups ui working with amino support in the meantime while continuing to investigate a solution to #84.

I pulled this locally, then run yarn build and then using yarn link to use my local version of @regen-network/api in groups-ui ryan/10-amino-signing-support but I still get typescript errors in dev or build...
Maybe I have something wrong in my set up or I've missed a step, I haven't dug too much into it at this point.

Other than that I'm fine with those changes so we can move forward with that, as long as we add a note in the README about that, so pre-approving.

Hmm... I'm not sure. I was importing the local package in package.json to test. I haven't used yarn link before. I remove the node modules and rebuild with the local import to test. Probably not the most efficient but it does the trick. I just double checked to make sure and build and dev in groups-ui seems to be working for me.

If you run yarn build, you will overwrite the changes here. Maybe that's what happened?

It might also have been strict mode being set within groups ui (see regen-network/groups-ui@29e58c4). I was using this locally when testing as well and had not committed to the groups pull request yet.
