v0.7.0-alpha.0

Added

• Support for unit tests!

Changed

• Breaking: probe-rs reads the test cases directly from the ELF file instead of querying them from the target via
  semihosting.
• Breaking: global setup function must now be annotated with an attribute #[embedded_test::setup]
  instead of passing it to #[embedded_test::tests(setup=...)].
• Linker script now lives in its own crate embedded-test-linker-script, to allow keeping embedded-test in
  [dev-dependencies].

Fixed

• Ensure embedded-test.x is only augmenting (instead of replacing) the linker scripts on std
