Missing CVM codes in the ITR from years 2010 to 2019

[glourencoffee]

Description

The exception ValueError is raised if AccountLayoutType.from_cvm_code() is called for ITR documents from years 2011 to 2019.

Steps to reproduce

1. Download an ITR from 2011 to 2019
2. Open the document with DFPITRFile
3. Call AccountLayoutType.from_cvm_code() for documents in that file
4. See how ValueError is raised for many documents

Expected behavior

CVM codes in ITR files from 2011 to 2019 should be tracked by this library, and thus not raise ValueError.

Actual behavior

For example, running the following program:

import cvm
import sys

missing_cvm_codes = {}

with cvm.DFPITRFile(sys.argv[1]) as file:
    for dfpitr in file:
        # print(dfpitr)
        
        try:
            cvm.AccountLayoutType.from_cvm_code(dfpitr.cvm_code)
        except ValueError:
            missing_cvm_codes[dfpitr.cvm_code] = dfpitr.company_name

# print('CVM codes missed by this library:')
for cvm_code, company_name in missing_cvm_codes.items():
    print(cvm_code, '-', company_name)

with the ITR of 2011 produces the following output:

Additional context

This bug results from the refactor implemented by #11. #20 was a similar bug with DFP files.
