AggregatedTranscript() signature incorrect in .pyi

[fjarri]

ferveo/__init__.pyi has:

class AggregatedTranscript:

    def __init__(self, messages: Sequence[Tuple[Validator, Transcript]]):
        ...

But AggregatedTranscript::new is defined in the bindings as

#[pymethods]
impl AggregatedTranscript {
    #[new]
    pub fn new(messages: Vec<ValidatorMessage>) -> Self {

where ValidatorMessage is not exported.

Same problem with AffregatedTranscript.verify() and Dkg.aggregate_transcripts(). This is also repeated in the copy of the type stubs in nucypher-core.

I don't think it's possible to a tuple definition from Rust pyo3:

#[derive(FromPyObject, Clone)]
pub struct ValidatorMessage(Validator, Transcript);

I will replace ValidatorMessage with a pyclass, which is a breaking change fo nucypher.
