The new src/compat/react-native.ts polyfill module and the test fixture are what we want. Net 970 line deletions in the diff means it's also reverting the JSDoc additions in develop, same rebase situation as several other open PRs.

git fetch origin
git rebase origin/develop
# during the rebase, keep your new files (src/compat/*, test/compat/*)
# drop your changes to src/chains/stellar/* and test/chains/stellar/* in favour of develop's versions
git push --force-with-lease

Once the diff is just your additions, this is ready. Thanks @Buchi-Einstein.

Clean rebase, just your src/compat/react-native.ts polyfill module, the Expo example, the compat test, and the small SDK changes. Merging. Thanks @Buchi-Einstein.
