feat(helpers): introduce multiple method

[ST-DDT]

Adds a new method to generate multiple values from a method.

In our code we have a few of places that generate multiple values from a single method:

• faker/src/modules/system/index.ts

  Lines 80 to 81 in 8bf7162

  	const extensionsStr = Array.from({ length: extensionCount })
  	.map(() => this.fileExt())

• faker/src/modules/string/index.ts

  Lines 163 to 165 in 02f3967

  	return Array.from({ length }, () =>
  	this.faker.helpers.arrayElement(charsArray)
  	).join('');

• faker/src/modules/color/index.ts

  Lines 323 to 325 in 79858fe

  	color = Array.from({ length: 3 }).map(() =>
  	this.faker.datatype.number({ min: 0, max: 255 })
  	);

• faker/src/modules/datatype/index.ts

  Lines 301 to 303 in 838f836

  	return Array.from<string | number>({ length }).map(() =>
  	this.boolean() ? this.faker.string.sample() : this.number()
  	);

• faker/src/modules/finance/index.ts

  Line 345 in 838f836

  return Array.from({ length }, () => this.faker.datatype.number(9)).join('');

• And probably the whole lorem module
• And others that use a loop right now

Example

faker.helpers.multiple(faker.person.firstName) // [ 'Aniya', 'Norval', 'Dallin' ]
faker.helpers.multiple(faker.person.firstName, { count: 3 }) // [ 'Santos', 'Lavinia', 'Lavinia' ]
faker.helpers.multiple(faker.person.firstName, { count: 3, unique: true }) // [ 'Santos', 'Nedra', 'Lavinia' ]

Planned features

• Dynamic result count / range (requires feat(helpers): add rangeToNumber method and add range parameters #1486)
• Generate unique elements per array (requires another PR)

[ST-DDT]

Blocked till #1486 is merged.

• feat(helpers): add rangeToNumber method and add range parameters #1486
