// The following table translates an ascii subset to 6 bit values as follows
// (see rfc 1521):
//
//  input    hex (decimal)
//  'A' --> 0x00 (0)
//  'B' --> 0x01 (1)
//  ...
//  'Z' --> 0x19 (25)
//  'a' --> 0x1a (26)
//  'b' --> 0x1b (27)
//  ...
//  'z' --> 0x33 (51)
//  '0' --> 0x34 (52)
//  ...
//  '9' --> 0x3d (61)
//  '+' --> 0x3e (62)
//  '/' --> 0x3f (63)
//
// Encoded lines must be no longer than 76 characters.
// The final "quantum" is handled as follows:  The translation output shall
// always consist of 4 characters.  'x', below, means a translated character,
// and '=' means an equal sign.  0, 1 or 2 equal signs padding out a four byte
// translation quantum means decoding the four bytes would result in 3, 2 or 1
// unencoded bytes, respectively.
//
//  unencoded size    encoded data
//  --------------    ------------
//     1 byte		"xx=="
//     2 bytes		"xxx="
//     3 bytes		"xxxx"
