Wrong version check

[Simsalabim1234]

The check in https://github.com/danielhrisca/asammdf/blob/master/src/asammdf/blocks/mdf_v4.py#L390C21-L390C45 is wrong. Python compares character by character, and this fails in our case, where we have
version_str = '4.20'
Note that for version_str = "4.20" 'it would succeed, but for some reason it has the double quotes in the version_str variable.

'4.20' and "4.20" are the same thing

That is not my main point. Take "4.9" > "4.10". This would be True with the current code because 9 is larger than 1 (python compares position by position).
