[Proposal] Profiling in snarkvm-console-collections should be optional

[MauroToscano]

💥 Proposal

aleo-std crate is used for profiling in snarkvm-console-collections . This crate and its invocations should be enabled with an independent feature.

src/merkle_tree/mod.rs is the only file on snarkvm-console-collections using this crate for profiling

The uses of timer and lap can be wrapped with a cfg feature enabled as needed
