Builds failing -- dependency conflict with the serde package

[swcurran]

Per PR #31, it looks like the serde package is locked to a version (1.0.152) in this package, but a later version is required by another dependency. There is a dependabot PR for serde, but even that doesn't look like it would satisfy the other dependency path (see log below):
