[Feature Request] Add SP (Swift Package) and Android libraries as part of the release process

[kcw-grunt]

Background

People are using ltcsuite/lnd to use in their projects and it is a great resource to promote use the features in the Litecoin ecosystem.

For mobile clients like Android & iOS, leveraging the ltcsuite/lnd library is not as automated as desired. Rather than the CI/CD creating a docker space to create a binary from source, it would be ideal for the mobile client needing the package(s) to simply pull the SDK by referencing the commit or release tag

Adding via SPM

For iOS the most streamlined method to add ltcsuite/lnd would be to add it to the package manifest or look it up in Xcode Swift Package Manager

For example using a Package.swift file:

// swift-tools-version:5.3
import PackageDescription

let package = Package(
    name: "LTCSuite_lnd",
    products: [
        .library(name: "LTCSuite_lnd", targets: ["LTCSuite_lnd"]),
    ],
    dependencies: [
        .package(url: "https://github.com/ltcsuite/lnd.git", from: "v0.14.2-beta.rc2"),
    ],
    targets: [
        .target(name: "LTCSuite_lnd", dependencies: ["KeychainAccess"]),
    ]
)
