tinycbor: Version bump to 0.5.2

This release fixed some bugs related to disabling float support in the
parser.
The float support is now optional and can be enabled by including the
tinycbor_float module. This allows for compiling on AVR as that platform
doesn't support the float specific defines used by tinycbor.
