CanonicalHex receives an input and return it's canonical form, i.e.

ConcatHex concatenates sanitized hex strings.

PrefixedHex is CanonicalHex but with 0x prefix.

SanitizeHex removes the prefix `0x` if it exists and ensures there is an even number of characters in the string, padding on the left of the string is it's not the case.

splitInBoundedChunks split the line in `count` chunks and returns the slice `chunks[1:count]` (so exclusive end), but will accumulate all trailing chunks within the last (for free-form strings, or JSON objects).

splitInChunks split the line in `count` chunks and returns the slice `chunks[1:count]` (so exclusive end), but verifies that there are only exactly `count` chunks, and nothing more.

BlockReader reads the dbin format where each element is assumed to be a `bstream.Block`.

BlockWriter reads the dbin format where each element is assumed to be a `bstream.Block`.

ConsoleReader is what reads the `geth` output directly.
