[ADD] missing PointField type entries

[wodtko]

Description

Adding missing entries in the PointField message definition.
The current PCL uses more types than currently available in the message definition.
However, some Python libraries expect to find the datatype values in the message definition.

Fixes #300

Is this user-facing behavior change?

Users may use int64, uint64 and bool in PointClouds and have an easier life decoding them

Did you use Generative AI?

No

Additional Information

https://github.com/PointCloudLibrary/pcl/blob/master/common/include/pcl/type_traits.h
this is where the PCL defines the values

i think this makes sense and align with https://github.com/PointCloudLibrary/pcl/blob/master/common/include/pcl/type_traits.h.

i would like to have another review before merge.

Filling these out to match pcl's definition makes sense.
