New features
This is a stable version including the following features:
- The `CCP3D` has been added to this module, suitable for calculated mantle transition structure. Please refer to [Xu et al., 2018](https://www.sciencedirect.com/science/article/abs/pii/S0012821X17306921).
- We have written the `rfani.py` for estimating crustal anisotropy using a joint method in [Liu and Niu 2012](https://academic.oup.com/gji/article/188/1/144/632605).
- We write a `ccpprofile.py` instead of the `ccp.py`. The `ccp_profile` was rewritten to a class.
- New criteria have been added to `RF`:
- Remove RFs with final RMS large than `rmsgate`.
- Remove RFs with summed energy after 5s less than 0.1.
- Add Water level deconvolution in `decon.py`.
- Add LQT option in command `prf`.
- `pickrf` now supporting virtual check with the only R component.
Bug fix
- Fix bugs in CCP stacking when `stack_val` is not equal to `dep_val`.
- Fix bugs in associating data and events when reference time in SACHeader is the origin time.
