Problem to solve
Add a general hat function to replace the current vec2skew
Further details
Besides so3, which has a 3x3 skew matrix, all the rest of se3, sim3, etc types have the the closed form representation of the hat matrix, which are used pretty often.
Proposal
For each Lie Type, create a corresponding hat function.
Documentation
Args: input (LieTensor): The input LieTensor (Lie algebra)
Return: a matrix representing the hat operation
Testing
No risk.
