Get-GUIDandDeclare

把 _GUID_b5d30521_b5b3_4f9d_9748_5e3e1636e0bf 转换成 GUID 数据，顺便生成声明：

用法：

Get-GUIDandDeclare _GUID_b5d30521_b5b3_4f9d_9748_5e3e1636e0bf

Name                           Value
----                           -----
FullDeclare                    // b5d30521-b5b3-4f9d-9748-5e3e1636e0bf...
GUID                           b5d30521-b5b3-4f9d-9748-5e3e1636e0bf
Declare                        { 0xb5d30521, 0xb5b3, 0x4f9d, { 0x97, 0x48, 0x5e, 0x3e, 0x16, 0x36, 0xe0, 0xbf } }

或者

Get-GUIDandDeclare _GUID_b5d30521_b5b3_4f9d_9748_5e3e1636e0bf ABCD -Single

// b5d30521-b5b3-4f9d-9748-5e3e1636e0bf
