Get IOTA transaction depth

According the schematic diagram as below, this tool will:

1. Give a specific IOTA transaction (TXN-A)
2. List all child transactions: txn(3), txn(4)
3. Get the approved milestone transaction: txn(5)
4. Calculate (A) IRI-depth: the depth from txn(7) to txn(4)

Example:

1. Modify the specific transaction hash on get_txn_deep.py:

   hash_transatcion = "SJXZIEIUAEIITGZEZGAGRMCFNFLYVAFC9NPQPOEP9KPGMH9UHDAXZIUD9CMRD9RXSMMVGZUDORX999999"

2. Run it

   $ python3 get_txn_deep.py

3. Output

   • Get milestone transaction hash: UZDVF9WDTPDIFAVSBXPMYWWHKQIVG9GCTMKFIBVYCZRQRRAJBONYWINLAPUOIVPCDQBKLKITIZDJZ9999
   • Get IRI-depth: 66878
