Format of Modality IDs

[foysavas]

Under the hood self-describing peerid like: 12D3KooWMRAdDAzYKfvPrN1R1Cf5fPC1iSLe37yUDV5FhEWsWABB

But format it like this:

1. convert to hexadecimal
2. copy first five hexadecimal after prefix to front
3. prefix with 0x

Example:

1. 002408011220ac5ad4ff4c9bb3c92ac2e18f0619ff5c7c2805c08947b01fff1d160e148dfa9a
2. ac5ad002408011220ac5ad4ff4c9bb3c92ac2e18f0619ff5c7c2805c08947b01fff1d160e148dfa9a
3. 0xac5ad002408011220ac5ad4ff4c9bb3c92ac2e18f0619ff5c7c2805c08947b01fff1d160e148dfa9a

as recommended by @rarepepi

Reasoning:

1. 0x familiarity to eth devs
2. keep self-describing key type allowing cryptographic upgrades
3. beginning and end of key of id distinctive (example 0xac5ad...dfa9a) an key format still easy to find starting at fixed width
