backwards compatibility with ucan 0.8?

Summary

Originally posted on discord

Problem

A UCAN encoded from nftstorage/ucan-storage is not accepted by rs-ucan because of the missing field ucv.

found via git blame that in <v0.9 ucv was in the header, and in 0.10 in the payload..

Impact

Can't use TS-ucan with rs-ucan

Solution

Posted an issue to update TS-ucan ucan-wg/ts-ucan#105 ...

but what about backwards compatibility?
Too much work for pre-1.0?
Or actually wanted?

FYI - This ts lib is compatible with UCAN spec 0.10 and seems to be the successor to ts-ucan
