Matrix Class rotateX, rotateY and rotateZ methods assume the provide angle is in radians

The rotateX, rotateY and rotateZ methods of the Matrix class assume the angle of rotation is in radians not degrees like all of the other cadquery methods.
```python
import cadquery as cq
import math

print("Unit X Vector rotated about the Z axis by 30 degrees:(",math.cos(math.radians(30)),",",math.sin(math.radians(30)),",0)")
unitXVector = cq.Vector(1,0,0)
m0 = cq.Matrix()
m0.rotateZ(30)
rotatedUnitXVector = m0.multiply(unitXVector)
print("Unit X Vector rotated by rotateZ(30):",rotatedUnitXVector)

m1 = cq.Matrix()
m1.rotateZ(math.radians(30))
rotatedUnitXVector = m1.multiply(unitXVector)
print("Unit X Vector rotated by rotateZ(math.radians(30)):",rotatedUnitXVector)
```
There is one line fix:
```python
def _rotate(self, direction: gp_Ax1, angle: float):

new = gp_Trsf()
# new.SetRotation(direction, angle)
new.SetRotation(direction, math.radians(angle))

self.wrapped = self.wrapped * gp_GTrsf(new)
```
However, this will break backwards compatibility.
