Adjust version information to use struct and not *.s19 informaiton

[AndreasFreund]

User story

1. As a developer
2. I need to include version information in the s19 file
3. So that the customer can know what software version he is flashing

Acceptance criteria

• When getting any version information from the s19 file, take it from the struct and not the header
• Still display the s19 header when opening a file (but only in developer mode)

Struct

struct data{
	uint64_t magic_number;
	char asw_version[8];
	char asw_version_comment[40]; // e.g. Bremse vorne links
	uint64_t magic_number2;
}
