compress/flate: use seperate const block for exported constants

As rendered on https://tip.golang.org/pkg/compress/flate/, there is an
extra new-line because of the unexported constants in the same block.

<<<
const (
    NoCompression      = 0
    BestSpeed          = 1
    BestCompression    = 9
    DefaultCompression = -1
    HuffmanOnly        = -2 // Disables match search and only does Huffman entropy reduction.

)
>>>

Instead, seperate the exported compression level constants into its own
const block. This is both more readable and also fixes the issue.
