Investigating Java bindings and bindings generator for Java (for FIT-Connect Java SDK)

Motivation/Context:

• We have no experience with Java bindings and rust-sdk so we need to investigate the options
• FIT-Connect provides java support so we need to provide support for that as well
• There are 2 options for java (kotlin or java bindings exist). We need to decide on one of them.

Scope:

• This ticket will provide evidence for confirming the logical approach in #33

Time box:

Result/ACs:

• Decide which of the 2 options we want to use
• Document steps taken to make these bindings happen

Notes/Hints/Ideas:

• #348 (comment 475302)
