Gather unknown signatures

[pipermerriam]

What is wrong?

While scanning the webserver logs today I noticed that there are a lot of queries to the API for signatures which are not found in the database. These queries potentially represent important gaps in the available signature data.

How can it be fixed

It may be interesting to occasionally gather these and see if we can uncover the corresponding plain text function signatures.

In theory, this data could also be gathered by simply scraping the entirety of the historical transactions and extracting the first four bytes, skipping over transactions that are contract creations. The bonus of doing it this way is that we would also have a contract address to investigate which may have verified source code attached to it on etherscan.
