fix(xmr): add missing view_tags to hf15

[ph4r05]

Adds support for view-tags monero-project/monero#8061, new HF15 feature that was missing in the recent PRs. @selsta pinged me with this missing feature monero-project/monero#8299 (comment)

As wallet is using view_key to derive view tags, tx receiving code on the wallet side does not require changes.

PR is related to the:

• XMR: HP15 support, implement BulletproofPlus, refactor and cleanup #2232
• Monero hackathon results #2219
• feat(trezor): add HF15 support, BP+ monero-project/monero#8299
• Add view tags to outputs to reduce wallet scanning time monero-project/monero#8061

@matejcik PR is ready for review, testing binary was released https://github.com/ph4r05/monero/releases/tag/v0.17.3.2-dev-tests-u18.04-03 shasum256 3280aeef795baf2fc46687c07ac4131e5a18767ecdd3af83cf17823ebb2d1007

I've modified CI nix file to use a new binary.

HF15 will be activated on 16th July 2022 according to the https://www.getmonero.org/2022/04/20/network-upgrade-july-2022.html

[matejcik]

our release will be August 17th at the soonest.

will Trezor continue to work after HF15 or will it just be broken?

[ph4r05]

@matejcik After HF15 is activated, the last public trezor firmware wont be able to sign transactions, so the integration is broken until new firmware release is out. (Assuming HF15 changes are enforced after the fork, I asked selsta about it in the monero PR).

The only way for users being able to sign their transactions is to build their custom firmware or install unverified builds :/

[matejcik]

CI is horribly broken but that will hopefully go away with the merge

HF15 postponed to 13th August: https://www.getmonero.org/2022/04/20/network-upgrade-july-2022.html - so we don't have to push the FW update in July
