v0.10.0

PyGRT v0.10.0

This is a major update before releasing a stable version, primarily concerning the execution style of the C program (the Python interface remains unaffected). Recognizing that compiling multiple executables would significantly hinder future maintenance and feature expansion, and considering the current early-stage program isn't too complex yet, I decided to implement this change promptly.

Inspired by Git and GMT programs, PyGRT will now compile into just one executable — grt — starting with this version. Similar to GMT, it will invoke different modules to perform various computational functions, for example:

# Calculate Green's functions (equivalent to the old 'grt' command)
grt greenfn [arg1] [arg2] ...
# Synthesize theoretical seismograms (equivalent to the old 'grt.syn' command)
grt syn [arg1] [arg2] ...
# Calculate static Green's functions (equivalent to the old 'stgrt' command)
grt static greenfn [arg1] [arg2] ...
...

grt and each module's help documentation can be printed using -h. The online documentation has been updated accordingly, and all example scripts have been modified to reflect these changes.
