cortex-m-rt v0.7.0 support

[pdgilbert]

(Related to #283)

I need cortex-m-rt v0.7.0 to avoid conflicts with other crates. The github version CHANGELOG.md is reporting

Support cortex-m-rt v0.7.0 but still allow v0.6.13 (#283)

but there seems to be a problem that stm32f3 is specified in Cargo.toml as

stm32f3 = { version = "0.13.2", default-features = false }

I think cortex-m-rt v0.7.0 support in stm32f3 is only introduced in 0.14. I get

error: failed to select a version for `cortex-m-rt`.
    ... required by package `stm32f3 v0.13.2`
    ... which is depended on by `stm32f3xx-hal v0.8.1 (https://github.com/stm32-rs/stm32f3xx-hal#91b47e12)`
    ... which is depended on by `rust-integration-testing-of-examples v0.1.0 (/home/paul/githubClones/rust-integration-testing/dev-testing)`
versions that meet the requirements `^0.6.10` are: 0.6.15

the package `cortex-m-rt` links to the native library `cortex-m-rt`, but it conflicts with a previous package which links to `cortex-m-rt` as well:
package `cortex-m-rt v0.7.0`
    ... which is depended on by `rust-integration-testing-of-examples v0.1.0 (/home/paul/githubClones/rust-integration-testing/dev-testing)`

failed to select a version for `cortex-m-rt` which could resolve this conflict

0.7 Support is currently only in master and not yet released: https://github.com/stm32-rs/stm32f3xx-hal/blob/master/CHANGELOG.md#added

Have you tried compiling with the current master?

Using the [patch] manifest, if you are using stm32f3xx-hal as a depency should be the easiest way to test it out.

I'm using the current master stm32f3xx-hal#91b47e12. Are you saying I need to patch too?

[pdgilbert]

FWIW I tried github.com/Sh3Rm4n/stm32f3xx-hal?branch=pac-upgrade#9e59ee1ad280609c48e3361cc9f82a7ac6285c05 and all my tests are working. (At least all the ones that are not broken for other known reasons.) CI at https://github.com/pdgilbert/rust-integration-testing/actions

Ah finally I understand the problem. #283 is solving a problmen, which isn't to solve, because stm32f3 expects a fixed versino cortex-m-rt-0.7.0 for v0.14.0 and cortex-m-rt-0.6.x for v0.13.1? If than, yes #282 should fix the problem.

[pdgilbert]

My guess is that is correct. (I'm still a newbie so it is just a guess.)
