[TASK] Generate EigenLayer AVS from templates with cargo-tangle

[Tjemmmic]

Overview

Tangle - Current option

Similar to creating Tangle blueprints from the blueprint template with:

cargo tangle blueprint create --tangle

EigenLayer - New options

An equivalent should be made for EigenLayer:

cargo tangle blueprint create --eigenlayer <TYPE>

where you can use bls or ecdsa as the Type, determining which template is used. Omitting the type will default to bls.

Default

Leaving out Tangle or Eigenlayer defaults to Tangle:

cargo tangle blueprint create
