Added nanoid.Canonic() which is direct to nanoid.Standard(21). Made comments briefer, added a note in README about memory use.

License changed to GPL-3.0. Docs at https://pkg.go.dev/github.com/jaevor/go-nanoid.

go-nanoid v1.2.0

New function:

• ASCII(length int) for creating a Nano ID generator which uses an ASCII alphabet ranging 40-126 inclusive.

Also, cleaner docs and exported the errInvalidLength error.

go-nanoid v1.1.0

New functions:

• CustomASCII(alphabet string, length int) for creating a Nano ID generator which uses an ASCII alphabet.
• CustomUnicode(alphabet string, length int) for creating a Nano ID generator which uses a unicode alphabet. The difference between these two is that CustomASCII uses way less memory and is faster than CustomUnicode, so use whichever one makes sense.

Custom is now an alias to CustomUnicode

go-nanoid v1.0.0

• Standard(length int) for generating Nano IDs ranging from 2-255 chars using the canonic A-Za-z-0-9_- alphabet.
• Custom(alphabet string, length int) for generating Nano IDs ranging from 2-255 chars using a custom alphabet.
