`CBOR.decode("A\x00")` returns empty string instead of `"\x00"`

Hi,

Is the following expected?

$ irb
irb(main):001:0> require "libcbor/all"
.gem/ruby/2.6.5/gems/libcbor-0.1.0/lib/libcbor.rb:50: warning: constant ::Fixnum is deprecated
=> true
irb(main):002:0> CBOR.decode("C\x01\x02\x03")
=> "\x01\x02\x03"
irb(main):003:0> CBOR.decode("C\x01\x00\x03")
=> "\x01"
irb(main):004:0> CBOR.decode("A\x00")
=> ""

I mean the last two decode return values.

No. cbor-ruby happens to produce the correct answers:

$ irb -rcbor
>> CBOR.decode("C\x01\x02\x03")
=> "\x01\x02\x03"
>> CBOR.decode("C\x01\x00\x03")
=> "\x01\x00\x03"
>> CBOR.decode("A\x00")
=> "\x00"
