More Bluetooth 5.0+ packets

[sacca97]

Currently draft, what is missing:

• unit tests (WIP)
• regression tests
• Not sure formatting is fine (although it respects the guidelines)

Introduces various stuff from Bluetooth 5.0+ plus some standardized field naming across packets for clarity and interoperability. Additionally covers an edge case in the HCI command handling.

I am currently using this code for testing actual BLE devices and """it works""". I'll add tests (and modify existing ones) asap, please advice if I may skip some tests as not everything may be necessary.

What was added:

• HCI_LE_Meta_Enhanced_Connection_Complete
• HCI_Cmd_LE_Set_Extended_Advertising_Parameters
• HCI_Cmd_LE_Set_Extended_Advertising_Data
• HCI_Cmd_LE_Set_Advertising_Set_Random_Address
• HCI_Cmd_LE_Set_Extended_Scan_Parameters
• HCI_Cmd_LE_Set_Extended_Scan_Enable
• HCI_Cmd_LE_Extended_Create_Connection
• HCI_Cmd_LE_Set_Event_Mask (update 8-byte bitmask)

What was modified:

• atype / oatype / datype --> own_addr_type, peer_addr_type, or addr_type.
• address / paddr / daddr --> addr or peer_addr
• HCI receive now checks r.code in (0x0e, 0x0f) to cope with commands such as "Create Connection" which is async and returns a "Pending" status.

Thanks for your pr. could you please revert all changes introduced from your code formatter.
