Size-in-bytes conversion should be explicitly (not optionally) specified by user using size | <size>. Unless this is explicitly specified, tscfg should assume it is a string by default; no implicit conversion should be done. (This is also the default behaviour of Typesafe Config.)

Example:

In each of the following cases, tscfg currently generates a variable memory of type Long, with value 53687091200.

memory: 50G
memory: "50G"

To be consistent with the default behavior of Typesafe Config, which doesn't make assumptions about types unless explicitly requested (e.g., using methods such as getBytes, getInt, etc), tscfg should instead generate a variable memory of type String, with value "50G". This should be the default behavior, unless the user explicitly requests a size-in-bytes comparison as follows:

memory: "size | 50G"

(This has been discussed at length in #41).
