Prover.toml doesn't handle arrays of structs

[joss-aztec]

Aim

Arrays of structs should handled

Expected Behavior

Given the program

struct Foo {
    bar: Field,
    baz: Field,
}

fn main(foos: [Foo; 3]) -> pub Field {
    foos[2].bar + foos[2].baz
}

And the Prover.toml

[[foos]]
bar = 0
baz = 0

[[foos]]
bar = 0
baz = 0

[[foos]]
bar = 0
baz = 1

nargo should be able to prove

Bug

Instead you encounter:

Error: input file is badly formed, could not parse, TOML parse error at line 3, column 1
  |
3 | [[foos]]
  | ^^^^^^^^
data did not match any variant of untagged enum TomlTypes

To Reproduce

1. prove the above program and input
