This includes a major breaking change, as it modifies how
KeymaskEncoder
gets seeded. This change was not 100% necessary, however it makes the initialization of the Base24 encoding alphabet slightly more efficient.Hostnames and subdomains are case-insensitive, so standard keymasks cannot be used there. This PR adds a new mode ("safe mode") that avoids the use of uppercase characters, while otherwise staying true to the design principles of the standard mode.
Safe mode is triggered with a boolean switch on the constructor options. API otherwise remains the same, bearing in mind that the block length is 14 characters in safe mode, rather than the standard 12.
