Feat: bump dependency versions, fix examples, move to defmt, new examples

[jkelleyrtp]

I've verified that these examples do work:

• [x] blink.rs
• [x] dw1000_delayed_tx.rs
• [x] dw1000_id.rs
• [x] dw1000_only_rx.rs
• [x] dw1000_only_tx.rs
• [x] dw1000_ranging_anchor.rs
• [x] dw1000_ranging_tag.rs
• [x] (new!) dw1000_ranging_basestation.rs
• [x] (new!) dw1000_ranging_mobile_tag.rs
• [x] dw1000_reg_modify.rs
• [x] dw1000_reg_rw.rs
• [x] dw1000_reg_short.rs
• [x] dw1000_rx_tx.rs
• [x] dw1000_subreg.rs
• [x] dw1000_subreg_ext_addr.rs
• [x] lis2dh12.rs
• [x] uarte.rs
• [x] uarte_heapless_string.rs

Updates:

• Ranging doesn't work right off the bat but the tags can talk with each other just fine. I think the logic and timing of the ranging examples need to be fixed.
• I had issues with RX/TX before upgrading the crates in both crates. After an upgrade nearly all the rx/tx examples work.
• Ranging examples work but are rather slow. Before I make this PR "ready" I want to make a more robust ranging example set.
• I made two new examples that work well with each other and don't have timeout issues.
• the nRF Timer1 seems busted in some way. Maybe I just don't understand embedded timers, but after it fires once it never fires again. Timer0 does not seem to have this issue.

After this PR is in, I'd like to start adding better support for antenna calibration (resolve #122) and some of the other low-hanging fruit in the issues tab.

Thank you, @jkelleyrtp, this is awesome!

Just ping me once this is ready, I'll do a full review then. If you want feedback about anything specific in the meantime, please let me know.

I'm just about done, but there's some noise because of how the crate is formatted. I've opened #147 as its own PR which will hopefully make this PR smaller.

Very excited for this :)

WRT resolving conflicts: do you prefer rebase or merge?

I prefer rebase before I submitted a review. After I submitted a review, I prefer additional changes to added as new commits.

Thank you, @jkelleyrtp, this is great!

I did a quick review, and can't find anything wrong (although I did leave one comment earlier, which turned out to be redundant). Since you've tested all the examples, I'm happy to merge this!

One nit pick for future reference: This would have been nicer to review, if there had been more focused commits, i.e. one for updating the dependencies, one for defmt, one for the new examples. But this PR overall was small enough to make the review still manageable, so no big deal.

Thanks again!

Ah yeah, I ended up rebasing everything into the single commit (old habits). Will focus on smaller commits in the future. Thanks! Hoping to add more soon.
