when doing wasme build, the tag/name is not required

[christian-posta]

when I do a wasme build . then I do a wasme list, I see the following:

ceposta@postamaclab(wasm-hub (master)) $ wasme list
NAME SHA      UPDATED             SIZE   TAGS
     5afbacf2 08 Feb 20 09:21 MST 1.0 MB latest

there is no name.

when I do wasme build --help, I see that "tag is supposed to be required"

  -t, --tag string               The image ref with which to tag this image. Specified in the format <name:tag>. Required

If it's required, we should fail the command if it's not provided. Im wondering if we could do the following, however:

wasme build . --name foo

Then we could default the tag to be something like webassemblyhub.io/foo

unless someone wants to specify the full tag, the can pass in --tag

thoughts?

mmm on second thought, I suppose we're trying to follow a similar approach to docker?
in that case, let's make -t required and fail the command if not there
