PR using paste crate which is in discussion whether we can use it or not with score-rust-infrastructure team.

[pawelrutkaq]

For me all fine except paste! crate usage as its not clear what to do with certificaiton of it,

[darkwisebear]

I would suggest to accept the change as-is and open a ticket so that we keep track of this issue. If we know how to treat external crates in safety critical code, we can keep it as-is if it gets qualified, or remove it at some point and resort to a proc macro. Other options like forking paste or reimplement it just do not make sense to me.

@darkwisebear @bharatGoswami8 fine with the approach for me. Maybe in code just mark that usage for paste! The crate is still under evaluation for safety and may be changed.
