Migrating from git defmt to stable defmt

NOTE this talks about migrating to defmt v0.1.x; v0.2.0 is on yet on crates.io!

On 2020-11-11, a stable version of defmt became available on crates.io. If you are still using the git version you are encouraged to migrate your project to the crates.io version! Two things need to be done to use the crates.io version of defmt:

1. change defmt, defmt-rtt and panic-probe dependencies from git to version "0.1.0" in relevant Cargo.toml-s
2. install version v0.1.4 (or newer) of probe-run

Here's are the exact steps for migrating an app-template project.

1. In your app-template project, change the root Cargo.toml as shown below:

 [workspace]
 members = ["testsuite"]

-[dependencies.defmt]
-git = "https://github.com/knurling-rs/defmt"
-branch = "main"
-
-[dependencies.defmt-rtt]
-git = "https://github.com/knurling-rs/defmt"
-branch = "main"
-
-[dependencies.panic-probe]
-git = "https://github.com/knurling-rs/probe-run"
-branch = "main"
-
 [dependencies]
+defmt = "0.1.0"
+defmt-rtt = "0.1.0"
+panic-probe = { version = "0.1.0", features = ["print-defmt"] }
 cortex-m = "0.6.4"
 cortex-m-rt = "0.6.13"

2. In your app-template project, also change the testsuite/Cargo.toml as shown below:

 name = "test"
 harness = false

-[dependencies.defmt]
-git = "https://github.com/knurling-rs/defmt"
-branch = "main"
-
-[dependencies.defmt-rtt]
-git = "https://github.com/knurling-rs/defmt"
-branch = "main"
-
-[dependencies.panic-probe]
-git = "https://github.com/knurling-rs/probe-run"
-branch = "main"
-# enable the `print-defmt` feature for more complete test output
-features = ["print-defmt"]
-
 [dependencies]
+defmt = "0.1.0"
+defmt-rtt = "0.1.0"
+panic-probe = { version = "0.1.0", features = ["print-defmt"] }
 cortex-m = "0.6.3"
 cortex-m-rt = "0.6.12"

3. Finally, install probe-run version v0.1.4 (or newer)

$ cargo install probe-run -f

Now you can resume working on your project!
