While extracting assets from the game "As Far As The Eye" I encountered some tuple and list index errors due to a shader having two platforms but just one program. This patch bails on the relevant loops when the lengths/programs are exhausted. There may be more appropriate behavior, such as serializing the same program for both platforms?

Here is a little bit of debug output I printed while troubleshooting this, for the problematic shader:

m_Shader.platforms is [<ShaderCompilerPlatform.kShaderCompPlatformOpenGLCore: 15>, <ShaderCompilerPlatform.kShaderCompPlatformVulkan: 18>]
m_shader.compressedLengths is (896,)
m_shader.decompressedLengths is (2504,)
shaderPrograms is [<UnityPy.export.ShaderConverter.ShaderProgram object at 0x7f3d2929dff0>]
