Add TED-LIUM 3 dataset

[jiwidi]

🚀 Feature

Hi! I saw torchaudio is missing the TED-LIUM dataset from https://arxiv.org/abs/1805.04699, https://www.openslr.org/51/ which is commonly used in ASR benchmarks and I would like to propose the addition of it to the list of avaliable datasets (And propose myself to code and contribute for it! :) )

Motivation

TED-LIUM is a very common dataset in ASR benchmarking tasks and we should include it on the library.

Pitch

Add TED-LIUM 3 dataset to the list of datasets

I would like to work in a PR to introduce it if it sounds good to the main contributors :)

Sounds good to me, and you can open a PR for this! Please make sure to follow the current dataset code organization when doing so :)
