Adds ByteByteGo guides and links (#106)

This PR adds all the guides from [Visual
Guides](https://bytebytego.com/guides/) section on bytebytego to the
repository with proper links.

- [x] Markdown files for guides and categories are placed inside
`data/guides` and `data/categories`
- [x] Guide links in readme are auto-generated using
`scripts/readme.ts`. Everytime you run the script `npm run
update-readme`, it reads the categories and guides from the above
mentioned folders, generate production links for guides and categories
and populate the table of content in the readme. This ensures that any
future guides and categories will automatically get added to the readme.
- [x] Sorting inside the readme matches the actual category and guides
sorting on production

+
+IDs are very important for the backend. Do you know how to generate globally unique IDs?
+
+In this post, we explore common requirements for IDs that are used in social media such as Facebook, Twitter, and LinkedIn.
+
+## Requirements:
+
+*   Globally unique
+
+*   Roughly sorted by time
+
+*   Numerical values only
+
+*   64 bits
+
+*   Highly scalable, low latency
+
+The implementation details of the algorithms can be found online so we will not go into detail here.
