Indigo ignores alternate name for templates in MOL v3000

[AlexeyGirin]

Steps to Reproduce

1. Go to Macro - Flex
2. Load from file: tadfile.zip

Actual behavior
System throws exception: Convert error! {}

This is because ATOM block uses alternate name (I) for BASE/Ind/I template

As per specification:

A template definition begins with a line that defines template properties, followed immediately with a
single CTAB block to provide the CTAB definition:
M V30 TEMPLATE index [ name | class/name[/alternate_name1[...] ]
[NATREPLACE=[class]/name/[altname]] [ COMMENT=template_comment

Currently Biovia supports only first alternate name (so it can reference two - name and alternate_name1 only) and parse mol files with many (I tried 4) alternate names.
I think we have to implement the same support

Expected behavior
System loads without errors
