Hello. Thank you for this tool.
I found a few small typos in the RequiredError class.
This is an error message I received:
```
Requires at most 2 options be used and 3were given from [filename,--get-size,--get-size2]
```
This PR changes the error message to
```
Requires at most 2 options be used but 3 were given from [filename,--get-size,--get-size2]
```
Happy to make changes as needed!
## Source
```cpp
std::string filename;
bool get_size = false;
CLI::App app{"Program to read a file specified as command-line argument"};
app.add_option("filename", filename, "File to read")->required();
app.add_flag("--get-size", get_size, "Print the size of the file");
app.add_flag("--get-size2", get_size, "Print the size of the file2");
app.require_option(1, 2); // Enforce only one flag can be input
CLI11_PARSE(app, argc, argv);
```
## Further Idea
Also, another idea I had was to remove required options from this error
message. In this example, "filename" is required, so a better error
message would be
```
Requires at most 1 options be used but 2 were given from [--get-size,--get-size2]
```
I'm happy to look into this if you feel it would be valuable
