Using of group.to_int leads to errors

[amyasnikov]

Python version: 3.10.12
TTP version: 0.9.4

Example of the error:

import ttp

template = '''
<group name="interfaces" to_int="mask">
interface {{name}}
 ip address {{address}}/{{mask}}
</group>
'''

data = '''
interface Ethernet0/1
 ip address 1.1.1.1/24
interface Ethernet0/2
 no ip address
'''

parser = ttp.ttp(template=template, data=data)
parser.parse()

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.10/site-packages/ttp/ttp.py", line 449, in parse
    self.__parse_in_one_process()
  File "/usr/local/lib/python3.10/site-packages/ttp/ttp.py", line 518, in __parse_in_one_process
    parserObj.parse(groups_indexes=input_obj.groups_indexes)
  File "/usr/local/lib/python3.10/site-packages/ttp/ttp.py", line 2628, in parse
    RSLTSOBJ.make_results(self.vars, raw_results, main_results=self.main_results)
  File "/usr/local/lib/python3.10/site-packages/ttp/ttp.py", line 2838, in make_results
    if self.processgrp() is not False:
  File "/usr/local/lib/python3.10/site-packages/ttp/ttp.py", line 3251, in processgrp
    self.record["result"], flags = self._ttp_["group"][func_name](
  File "/usr/local/lib/python3.10/site-packages/ttp/group/to_converters.py", line 19, in to_int
    v = data[k]
KeyError: 'mask'

Expected behavior: TTP ignores the absence of "mask" key for Ethernet0/2 and outputs the result without an error

And another one example

import ttp

template = '''
<group name="interfaces" to_int="trunk_vlan">
interface {{ name }}
 switchport trunk allowed vlan {{ trunk_vlan | split(',') }}
</group>
'''

data = '''
interface Ethernet0/1
 switchport trunk allowed vlan 5,10,15
'''

parser = ttp.ttp(template=template, data=data)
parser.parse()

Traceback (most recent call last):

    return self._ttp_[self.parent_dir][self.function_name](*args, **kwargs)
  File "/usr/local/lib/python3.10/site-packages/ttp/group/to_converters.py", line 21, in to_int
    data[k] = int(v)
TypeError: int() argument must be a string, a bytes-like object or a real number, not 'list'

Maybe it's a misuse of to_int, but it will be very useful to get a list of integers from a list of strings via this clause.

Hello, thank you for raising this issue, both requests should be addressed in 0.9.5, feel free to test and let me know how it goes.

Updated documentation with an example of how to use intlist variable to convert list of string into list of integers - https://ttp.readthedocs.io/en/latest/Groups/Functions.html#to-int
