dependencies: drop PATCH version requirements #923
Description
I'm using a project that depends on espflash as a transitive dependency. They recently updated their version of espflash, and this has caused a dependency resolution in my project.
espflash requires a very specific minimum version -- 0.4.27. This has changed since the previous release of 0.4.22.
I can't see what new features espflash depends on, or why older versions are no longer supported.
If it's not required, espflash should not require exact patch versions so that it plays nicer with other projects and reduces its build footprint to avoid accidentally having multiple versions of a crate included in a build graph. This goes for all dependencies, and not just log.
