PR 0001: Dot11 Element ID Extension and HE Operation

Scope:

• Adds Dot11EltExtension dispatch for Element ID 255.
• Adds Dot11EltExtensionGeneric for unknown or unsupported extension IDs.
• Adds Dot11EltHEOperation for Extended ID 36.
• Adds Dot11HE6GOperationInfo when the HE Operation element indicates that
  6 GHz operation information is present.
• Adds focused test/scapy/layers/dot11.uts tests for generic, short, HE, and
  HE 6 GHz extended elements.

Spec references used in code comments:

• IEEE Std 802.11ax-2021, 9.4.2.1 and Table 9-92: Element ID Extension.
• IEEE Std 802.11ax-2021, 9.4.2.249: HE Operation element.
• IEEE Std 802.11ax-2021, Figure 9-788k: 6 GHz Operation Information field.

Intentional partial support:

• Element ID Extension is a registry for many 802.11 information elements. This
  patch does not try to implement all of them.
• Unknown and unsupported extension IDs intentionally remain
  Dot11EltExtensionGeneric.
• EHT Operation and Multi-Link are left for separate follow-up patches so this
  first PR is reviewable on its own.

Focused test command used:

test/run_tests -t test/scapy/layers/dot11.uts -n 57-61 -F

Result:

PASSED=5 FAILED=0

Full dot11 suite note:

• A full test/scapy/layers/dot11.uts run reached and passed the existing
  tests up through Dot11EltVHTOperation in isolation before I interrupted it
  in this local environment because it was taking longer than expected.
  The focused tests for this patch passed.
