#### func  BytesToBlake2b

```go

```
BytesToBlake2b ignores all errors and gives you a blakae2b 64 hash value as a
byte slice. (or panics somehow)

#### func  CompareChecksums

```go

```
CompareChecksums will take in two byte slices, hash them with blake2b, and tell
you if the resulting checksums match.

```
Fprint is fmt.Fprint with error handling.
