Thanks for the help to https://stackoverflow.com/questions/42884196/bash-check-if-input-is-empty-in-pipe

Large files cause various problems
- can't be displayed in GitLab
- thus can't be edited or read there (accessibility)
- slow down recipemd on CLI
- slow down recipemd on CI
- also applies to recipemd-find worsening the whole usage
- slows down IDEA on my computer (yes...)

And to let actions speak louder than my complains the CI now enforces a
max file limit of 1 MB. Basically every file is way wayyyy smaller than
1 MB except when it's one of the troublesome files which easily exceed
them.

It was ALWAYS "Amount must start with a number".
This refers to amounts (yield and the ingredients).

An amount sometimes break when a comma is present outside a number.
An Amount NEEDS to start with a digit
for example:
VALID
*100 g* sugar
INVALID
*circa 100 g* sugar
*??? g* sugar
*a little bit* sugar
(!) It needs to start with a digit.

All of the errors have been due to this.
The CI server exists at first error but installing RecipeMD is quite easy.

I did:
```
for file in *.md
do
  echo "$file"
  recipemd -t "$file"
done
```
which worked quite fine. It only prints the title and not the whole recipe on success and prints the error message otherwise.
Very easy.

The comma in yield was the problem I assume recipemd tries to interpret it as a number with comma when a comma is present

Ich kann mich an das Rezept nicht mehr erinnern aber es war gut genug, dass ich mir selbst eine Notiz schrieb
