Upgrade to ESP-IDF 6.0.2

[eandersson]

This is a rough conversion as they completely migrated to MbedTLS 4.x and adopts the PSA Crypto API.
https://github.com/espressif/esp-idf/releases#release-v6.0

• Updated sha256 / TLS compatibility with 6.x.
• Updated Web Socket handshake.
• Fixed GCC 15.x compiler issues.

SV2 testing is required, if @STSMiner1 could do that would be appreciated, otherwise i will see if i can do a sv2 setup for testing

I'm surprised all the SHA256 constants and code is now needed.

They are needed. A follow-up could be a clean-up of the midstates, as only the BM1397 actually needs and uses them. For all other chips, midstate calculations are done but not used.

Saw on Discord the need for testing SV2. Using a DUO I updated the firmware using the unified update method. Have been running against a local Stratum SV2 UI instance for the past three hours. No issues observed so far. Hope this is helpful in some way.
