Currently, the escapeProxy works under the assumption that the
underlying reader will always return 1 byte at a time. Even though this
is usually true, it is not always the case, for example when using a pty
and writing multiple bytes to the master before flushing it.
In such cases the proxy reader doesn't work properly. For example with
an escape sequence being `ctrl-p,ctrl-q`, when the underlying reader
returns `ctrl-p,ctrl-q` at once, the escape sequence isn't detected.
This updates the reader to support this use-case and adds unit tests.

- use subtests to make it clearer what the individual test-cases
are, and to prevent tests from depending on values set by the
previous test(s).
- remove redundant messages in assert (gotest.tools already prints
a useful message if assertions fail).

In pkg/term/proxy.go and pkg/term/proxy_test.go, check if escapeKeys is empty and if it is, return the one key read
