Bump go to 1.22 and golangci-lint to 1.56.2

[nckrss]

• Update Go to 1.22
• Update golangci-lint to 1.56.2
• Correct new syntax lint errors
• Refactor crypto that was using deprecated functions
• Move golangci-lint run arguments to a configuration file

NOTE: Rather than disable the dot-imports rule for revive, an exclude directive should be used, however golangci/golangci-lint#4365 was not included in 1.56.2 so this PR disables a rule check that was added since 1.52. After the next release of golangci-lint the following can be applied:

diff --git a/.golangci.yml b/.golangci.yml
index 46a8a73..e4d95d5 100644
--- a/.golangci.yml
+++ b/.golangci.yml

If this PR is merged before the next golangci-lint release I will create a new draft PR to capture the update.

So sorry for the delays in review @nckrss, this and other active PRs here are in my backlog and I hope to get to it soon. Thank you for sending this!

Thanks so much for this change! Sorry for the delays here; busy Q1 at the day job. I especially appreciate you taking the time to migrate to the new ecdh crypto APIs!
