cargo-embed doesn't seem to support workspaces. This simple workspace project is to help debug issue #119.
This project can be built using cargo build from the root directory. However, attempting to use
cargo embed fails with:
$ cargo embed
error: package collision in the lockfile: packages common v0.1.0 (C:\path_to_workspace\common) and common v0.1.0 (C:\path_to_workspace\firmware\../common)
are different, but only one can be written to lockfile unambiguously
Error Failed to run cargo build: exit code = Some(101)
