[feat] implement `Encode` trait for structs that need it

[TAdev0]

77 introduced Encode trait and implemented it for Span<T> and ByteArray types. We also need to implement it for some structs that need it

[PavitraAgarwal21]

Can I take this issue

Hey @PavitraAgarwal21! Thanks for showing interest. We've created an application for you to contribute to Raito - Bitcoin ZK Client. Go check it out on OnlyDust!

Assigned @PavitraAgarwal21 You have to implement Encode for Transaction, TxIn, TxOut, and OutPoint pls feel free to ask any questions!

@lana-shanghai can we use the alexandria library

Which method do you need from Alexandria?

Why do you need it? For structs you need custom encodings. I would take a look at how it is done in pure Rust. You can reuse Alexandria of course, but in this context it doesn't have what you need imo

I'm exploring an alternative approach to implementing compact encoding, which typically relies on bit-shifting operations like shr and shl

There are shl and shr in utils

Hey I couldn't find a to_little_endian function. Can we create one to simplify compact size encoding and transaction serialization?

You can use append_word_rev to extend output buffer with a LE integer

hi @PavitraAgarwal21 , whats up with this issue?

[PavitraAgarwal21]

able to make the draft PR soon

@PavitraAgarwal21 we need to merge this, I'm reassigning the task (your contribution still counts though it's partial)
