Run NestJS on Fastify: the HTTP adapter with Fastify's plugins, JSON schemas and serialization.

/**
 * The chunks of a file, kept until it is buffered. The client decides how a
 * request body is cut (down to one byte per chunk with chunked transfer
 * encoding), the file stream passes those cuts on, and each chunk is a
 * Buffer of its own, which takes a few hundred bytes of memory whatever it
 * holds. Every run of `CHUNK_RUN_LENGTH` chunks is therefore merged into one
 * Buffer as soon as it is complete, so that a file being uploaded takes
 * memory for its size, which `limits.fileSize` bounds, rather than for its
 * number of chunks. A run whose chunks average `LARGE_CHUNK_SIZE` bytes or
 * more is kept as it is, as merging it would save little.
