Greetings!

Tag values for all data types, except for strings, are changed from
sequential binary values to ASCII printable ones. That way one may
easily remember the whole KEKS encoding table and recreate it from
the ground.

    tag     | old | new
    --------+-----+----
    EOC     | 00  | '.'
    NIL     | 01  | '!'
    FALSE   | 02  | 'f'
    TRUE    | 03  | 't'
    LIST    | 08  | 'L'
    MAP     | 09  | 'M'
    BLOB    | 0B  | 'B'
    +INT    | 0C  | '+'
    -INT    | 0D  | '-'
    NaN     | 10  | '_'
    +inf    | 11  | '>'
    -inf    | 12  | '<'
    FLOAT   | 13  | '~'
    TAI64   | 18  | 'T'
    TAI64N  | 19  | 'N'
    TAI64NA | 1A  | 'A'
    MAGIC   | 4B  | 'K' (not changed)
