Improved infrastructure pricing

What this post added

This post details Vercel's updated infrastructure pricing, which introduces more granular metrics for bandwidth and functions. It breaks down bandwidth into 'Fast Data Transfer' and 'Fast Origin Transfer', and functions into 'Function Invocations' and 'Function Duration'. New metrics like 'Edge Requests' and 'Data Cache Reads/Writes' are also introduced. The pricing changes aim to reduce costs for the majority of customers, align with industry standards, and provide new primitives for easier optimization. It also highlights existing features that help prevent runaway spend.
