Performance improvements

[carloscuesta]

Describe the bug

Hey! 👋🏼

Our cli can be improved when running and executing commands. In some scenarios and depending on the operating system some commands can take up to 1s to give some output.

See: #1096

Reproduction

This can be reproduced using the time command:

time gitmoji --help
time gitmoji --list
time gitmoji --search bug

As a result you'll get an output with the seconds each operation take to complete (for the given commands you'll get something like:

gitmoji --help  0.41s user 0.08s system 115% cpu 0.425 total
gitmoji --list  0.46s user 0.10s system 62% cpu 0.900 total
gitmoji --search bug  0.45s user 0.08s system 119% cpu 0.448 total

Additional context

We should explore the cli to understand if we can apply any improvements that impact the overall time commands take to complete.

Using dynamic imports might result in some easy wins for the initial startup.

gitmoji --help  0.41s user 0.06s system 108% cpu 0.426 total
node lib/cli.js --help  0.17s user 0.03s system 98% cpu 0.197 total
