[BUG] DateTime - Invalid isoformat string

[lieblinger]

The following issue pops up by printing a form with DateTime component and applies to latest version of python-formio-data (4.0):

ValueError: Invalid isoformat string: '2022-04-25T19:29:58.000Z'

Error to render compiling AST
ValueError: Invalid isoformat string: '2022-04-25T19:29:58.000Z'
Template: formio_report_qweb.report_formio_form_template
Path: /t/div/div[2]/t
Node: <t t-foreach="o._formio.components.items()" t-as="component">
                    <t t-set="component" t-value="component[1]"/>
                    <t t-call="formio_report_qweb.component"/>
                </t>

Date Format String in Form Builder Component:

dd/MM/yyyy HH:mm

I can't reproduce this datetime component (with your format) to store with the fraction 000Z.
Can you provide the full JSON of the component?

Apparently there's a need to parse the datetime value to cover such case.
I wasn't aware of this fraction, but found some info:

.000 is the fraction of a second and Z indicates UTC timezone.

@lieblinger possible to test this with the affected form and the latest version of the library?

I did some persing improvements in datetimeComponent.
